fix(test): add missing paths mock for provider factory tests

- Added mock for constants/paths.mjs to fix module not found errors
- Test results: 7 failed, 2800 passed (down from 8 failed, 2799 passed)

Remaining failures:
- 1 build-sea test (missing bootstrap.mts - structural refactoring)
- 6 provider factory tests (instance comparison issues with dynamic imports)
