🔧 Problem: Selfhost ParserBox doesn't recognize LOCAL keyword
- Only supports lowercase 'local' (Stage-1/2)
- Stage-3 mode with HAKO_PARSER_STAGE3=1 not working
✅ Solution: Add LOCAL keyword recognition in ParserStmtBox
- Check ctx.stage3_enabled() before parsing
- Support both 'local' and 'LOCAL' keywords
- Maintain backward compatibility with Stage-1/2
📍 Modified: lang/src/compiler/parser/stmt/parser_stmt_box.hako:109-149
- Added is_local_kw flag and kw_len variable
- Check 'local' first (always)
- Check 'LOCAL' if stage3_enabled() (conditional)
🐛 Current status:
- Using-chain parsing: ✅ SUCCESS (2 files)
- Stage-B test: ❌ Still failing with 'Unexpected token LOCAL at line 19'
- Next: Investigate which file's line 19 is causing the error
