Enhance RouteDetector to exclude specific directories from route detection

- Introduced a mechanism to exclude certain directories (e.g., node_modules, .venv) from route detection in the RouteDetector class.
- Added a new method, _should_include_file, to filter files based on the exclusion criteria.
- Updated route detection methods to utilize the new filtering logic for various frameworks (FastAPI, Flask, Django, Express, Go, Rust).
