chore(license): relicense from BSD-3-Clause to Apache 2.0 + Runtime Library Exception

Adopts the Swift/LLVM model: Apache License 2.0 with the Runtime Library
Exception text used verbatim by the Swift project. SPDX identifier:
Apache-2.0 WITH Swift-exception.

Apache 2.0 brings an explicit patent grant and patent-retaliation clause
that BSD-3 lacks. The Runtime Library Exception ensures binaries
produced by the Blaise compiler do not inherit attribution obligations
from the linked-in RTL.

* LICENSE — full Apache 2.0 + RLE text (replaces the deleted LICENCE).
* NOTICE — project header plus QBE attribution (MIT, vendored).
* docs/language-rationale.adoc — new Project Governance section
  capturing the decision, alternatives considered, and rationale.
* SPDX headers updated across all .pas, .pp, .inc, .c source files,
  build scripts, PasBuild plugins, and the Makefile.
* project.xml license field updated.
* tools/migrate_full.py HEADER template updated so generated
  self-hosting source carries the new licence.

+
+    TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+    1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+    2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+    3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+    4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+    5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+    6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+    7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+    8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+    9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+    END OF TERMS AND CONDITIONS
+
+    APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include

+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+== Project Governance
+
+=== Licensing
+
+==== Decision
+
+The Blaise compiler, RTL, and bundled tooling are licensed under the
+*Apache License, Version 2.0 with Runtime Library Exception*.
+
+The SPDX identifier used in source headers and project metadata is:
+
+  Apache-2.0 WITH Swift-exception
+
+The Runtime Library Exception text used is the one defined by the Swift
+project, reproduced verbatim at the foot of `LICENSE` in the project
+root. Binaries produced by the Blaise compiler that incorporate
+portions of the RTL do not inherit attribution obligations from the
+licence.
+
+==== Alternatives considered
+
+*BSD-3-Clause* — the project's original licence, in use during early
+development. Permissive, short, and well-recognised.
+
+* Rejected for one specific reason: it grants no patent licence. As
+  Blaise grows and accepts external contributions, every contributor
+  becomes a potential future patent risk under BSD-3. For a *compiler*
+  — which by nature implements algorithms (parsing, optimisation,
+  code generation) that may be patent-encumbered — this is the wrong
+  default.
+
+*BSD-3-Clause + custom patent grant + custom Runtime Library Exception*
+— a bespoke combination, ~50 lines.
+
+* Rejected because it is not OSI-approved, has no SPDX shorthand, and
+  trades concise text for unfamiliar text. A custom licence is *more*
+  friction for adopters' legal review than a 12-page Apache 2.0,
+  because every clause must be read from scratch rather than
+  recognised from precedent.
+
+*BSD-2-Clause-Patent* — an OSI-approved short licence with patent
+grant.
+
+* Rejected because it is not widely adopted in compiler/runtime land
+  and would still require a custom Runtime Library Exception bolted on,
+  putting us back in bespoke territory.
+
+*Modified-LGPL with linking exception* — the Free Pascal Compiler's
+licence, familiar to the Pascal community.
+
+* Rejected because it carries weak-copyleft obligations on the file
+  level. Apache 2.0 is fully permissive and avoids any ambiguity for
+  commercial adopters.
+
+*MIT* — minimal permissive licence.
+
+* Same patent-grant gap as BSD-3, but shorter. Same rejection.
+
+==== Rationale
+
+The Apache 2.0 + Runtime Library Exception combination is the modern
+consensus for compiler/runtime projects:
+
+* *Swift* (Apple) — Apache 2.0 with their Runtime Library Exception
+  text. The wording Blaise uses is theirs, verbatim.
+* *LLVM* — Apache 2.0 with the LLVM Exceptions (relicensed in 2019
+  from a BSD-style licence specifically to gain the patent grant).
+* *Rust* — dual MIT / Apache 2.0; Apache 2.0 is the patent-grant path.
+
+Specific properties that mattered for this decision:
+
+. *Explicit patent grant* (Apache 2.0 Section 3). Each contributor
+  grants users a patent licence covering their contributions. A
+  contributor who later sues a user over patents in their contribution
+  loses their grant. This is the headline feature versus BSD-3.
+
+. *Patent retaliation clause* (Apache 2.0 Section 3, second sentence).
+  Anyone who sues an Apache 2.0 user over the project loses their
+  licence. This deters submarine patent claims.
+
+. *Runtime Library Exception*. Without an exception, every binary
+  compiled by Blaise would technically inherit Apache 2.0 obligations
+  because the RTL is linked in. The Swift-style exception explicitly
+  releases that obligation, allowing closed-source applications to
+  ship binaries built with Blaise without Apache attribution noise.
+
+. *NOTICE file mechanic* (Apache 2.0 Section 4(d)). Concentrates
+  third-party attribution requirements (currently QBE) in one
+  well-known file that downstream redistributors must preserve.
+
+. *OSI-approved and SPDX-listed*. Tooling (FOSSology, ScanCode,
+  GitHub licence detection) recognises both the licence and the
+  exception identifier without configuration.
+
+. *Battle-tested in legal review*. Major compiler projects use exactly
+  this combination; corporate legal teams have pre-approved it.
+
+==== Notes
+
+* The relicensing happened pre-public-release. No external contributor
+  consent was needed because Graeme Geldenhuys was the sole
+  contributor at the time of the change.
+* All `.pas`, `.pp`, and `.inc` source files in `compiler/`, `rtl/`,
+  `tools/`, and `tests/` carry an `SPDX-License-Identifier:
+  Apache-2.0 WITH Swift-exception` header.
+* `LICENSE` at the project root contains the full Apache 2.0 text
+  followed by the Runtime Library Exception clause.
+* `NOTICE` at the project root contains attribution for vendored
+  third-party code (currently QBE under MIT).
+* `vendor/qbe/` retains its original MIT licence; QBE is invoked as a
+  subprocess and is not statically linked into the Blaise compiler.
