chore: merge master into feat/multi-tenants

- Resolved conflict in provider.py: merged rerank model support with tenant context
- Resolved conflict in telegram.py: kept async.to_thread optimization and added url parameter
- Resolved conflict in test_model_manager.py: kept both cloud runtime and rerank tests
