Successfully extracted utility methods from parser/mod.rs to common.rs:
- Created ParserUtils trait with token manipulation methods
- Extracted current_token, peek_token, advance, skip_newlines, etc.
- All parser modules now use trait-based utilities
- Reduced mod.rs by ~60 lines
✅ Build successful with no errors
