## Post-merge Fixes
- Synced `pyproject.toml` from upstream (conflict markers removed)
- Synced `lightrag/llm/openai.py` from upstream (missing function)
- Synced core modules: `lightrag.py`, `operate.py`, `constants.py`, `utils.py`, `shared_storage.py`

## Verification
- Core imports: ✅ `lightrag`, `LightRAG`, `compute_args_hash` all work
- Some test files may need updates due to API changes

## Next Steps
1. Run full test suite: `python -m pytest tests/ -m "not integration" --ignore=tests/gpt5_nano_compatibility`
2. Run integration tests with Postgres: `python -m pytest tests/ --run-integration`
3. Build and test webui: `cd lightrag_webui && bun install && bun run build`
4. Review and test multi-tenant features
