fix: Update FileWatcher tests to work with new RooIgnoreController interface

- Fixed FileWatcher test constructor to match new signature (removed ignore instance parameter)
- Added proper mocking for RooIgnoreController.initialize() method
- Enhanced ignore module mock to provide required add() and ignores() methods
- All code-index tests now pass (341/341)
