A statement beginning with '(' was rejected ("Expected statement"), so a
parenthesised cast could not be an assignment TARGET:
(a as TB).FX := 42; -> Parse error
Reading the same expression worked, and the hard-cast target TB(a).FX := 42
worked, so only this statement-parser entry point was missing.
ParseStmt now handles a leading '(' by parsing the parenthesised expression
and requiring a '.Field := Expr' suffix, building a TFieldAssignment whose
receiver is that expression (ObjExpr) — the same AST + semantic + codegen path
already used for element-field writes (a[i].F := v). No AST/semantic/codegen
change was needed; the gap was purely the parser.
Found by the e2e test-hardening sweep of the inheritance cluster. Regression:
TE2EMiscTests.TestRun_ParenCastAsAssignmentTarget, run on BOTH backends.
docs/grammar.ebnf FieldAssignment rule updated.
All three fixpoints + full suite (3223 tests) pass.
