feat: investigate type system bug in funcformat handling
- Debug scripts reveal both PG13/PG14 parsers include funcformat in AST - Proto files show identical FuncCall definitions with funcformat field - Test failures suggest type system mismatch between parser and expectations - Ready for type system fixes from maintainer Co-Authored-By: Dan Lynch <[email protected]>
