fix: resolve CI test failures by removing unused imports and updating workflow paths

- Removed unused imports from test files (os, pytest, pathlib.Path, MagicMock, patch, numpy, sqlite3, IndexingService)
- Updated CI workflow to only check shell-history-semantic-search project files instead of all files in shared src/ and tests/ directories
- All 43 tests pass locally
