Fix: Restore imports in check functions (autoflake-proof)

- Restored imports in _check_argos(), _check_deep_translator(), _check_langdetect()
- Used _ = module assignment to prevent autoflake from removing imports
- These imports test module availability by triggering ImportError if missing
- All 30 pre-commit hooks now passing
