Fix TProgram.Uses reserved-word clash (renamed to UsedUnits), nested brace-comment in uParser.pas, and missing uAST in Blaise.pas uses clause. Vendor QBE 1.2 source in vendor/qbe/ (built locally with make; binary excluded via .gitignore). End-to-end pipeline confirmed: Blaise compiles Hello World and Calc (6*7=42) to native x86_64 Linux binaries. 71/71 FPCUnit tests passing.
