- Add POST /api/v1/ingest/with-images accepting metadata (JSON Form) + images (UploadFile list)
- Stream images to temp storage and run pipeline inline with fresh AsyncSessionLocal
- Mark raw status=processing immediately to prevent queue worker race condition
- Add process_local_file() to ImageDownloader for handling already-downloaded images
- Split pipeline image processing: _stage_process_uploaded_images vs _stage_process_remote_images
- Process uploaded images sequentially to avoid SQLAlchemy concurrent flush errors
- Commit pipeline session explicitly after inline processing
- Clean up temp files in finally block regardless of pipeline outcome
- Add python-multipart dependency for FastAPI multipart parsing
- Update README with multipart endpoint docs and examples
