feat(typescript): update grammar and AST listener for new parser

- Update method calls and property accesses to match new grammar (e.g., `typeRef()` → `type_()`, `Identifier()` → `identifier()`)
- Refactor parameter and variable handling to support new AST structures
- Improve import parsing with new `importFromBlock` and namespace support
- Enhance arrow function and decorator detection with parent context traversal
- Add helper methods for position tracking and template string lexing
