Race conditions in useEffect hook caused navigation to invalid project IDs
to create multiple 'Untitled Project' entries. Users reported accumulating
885+ projects due to this bug.
This change adds global invalid project ID tracking across component remounts
and prevents race conditions through:
- Global invalidProjectIds Set in project store with tracking functions
- isInitializingRef to prevent duplicate initialization attempts
- Proper useEffect cleanup with cancellation tokens
- Specific error handling for 'not found' vs recoverable errors
- Removed problematic activeProject?.id dependency
Testing:
- Add comprehensive test suite (15 tests) with Vitest + React Testing Library
- Include integration tests demonstrating bug and validating fix
- Update CI pipeline to run automated tests
Fixes#182
