- #69: Embedding Generation Pipeline
* Created EmbeddingService with OpenAI integration
* Automatic embedding generation on entry create/update
* Batch processing endpoint for existing entries
* Async generation to avoid blocking API responses

* POST /api/knowledge/embeddings/batch - batch generation
* Comprehensive test coverage
* Full documentation in docs/SEMANTIC_SEARCH.md
Technical details:

Strict enforcement is now ACTIVE and blocking commits.
Updated documentation to reflect:
- Pre-commit hooks are actively blocking violations
- Package-level enforcement strategy
- How developers should handle blocked commits
- Next steps for incremental cleanup

BREAKING CHANGE: Strict lint enforcement is now ACTIVE
Pre-commit hooks now block commits if:
- Affected package has ANY lint errors or warnings
- Affected package has ANY type errors
Impact: If you touch a file in a package with existing violations,
you MUST fix ALL violations in that package before committing.
This forces incremental cleanup:
- Work in @mosaic/shared → Fix all @mosaic/shared violations
- Work in @mosaic/api → Fix all @mosaic/api violations
- Work in clean packages → No extra work required
Fixed regex to handle absolute paths from lint-staged.

Strict enforcement now active:
- Format all changed files (auto-fix)
- Lint entire packages that have changed files
- Type-check affected packages
- Block commit if ANY warnings or errors
Impact: If you touch a file in a package with existing violations,
you must clean up the entire package before committing.
This forces incremental cleanup while preventing new violations.
