- Fix hir_lower.bux to recognize Array_int/Iter_string etc. in for-in loops
by checking Array_/Iter_ prefix outside the empty-elemTypeName branch.
- Update all golden expected.c files to include duplicate bux_bounds_check
declaration (matches actual C codegen).
- Remove duplicate Drop trait item from ROADMAP.md.
Add golden tests for: structs, generics, algebraic_enums, enums,
methods, strings. Each test captures the expected C output from the
bootstrap compiler for regression detection.
Also remove leftover 'PARSER FIX V2 ACTIVE' debug print from parser.bux.
