fix: address review — fix signatures, use _captures, remove stale files

- Fix CSharpAnalyzer.resolve_import signature to match abstract (add Node type)
- Switch add_file_imports to use self._captures() instead of query.captures()
- Remove stale CI_OPTIMIZATION.md and test-project/b.py___
- Remove debug print from test
