Phase 4: Advanced Async Features (#4)
* feat: Initialize Phase 4 - Advanced async features
- Create PROGRESS_ADVANCED.md with detailed implementation plan
- Plan covers: cascade operations, context managers, transactions, aggregation
- Also includes: field projection, query optimization, and hybrid signals
- Comprehensive testing and documentation strategy included
* feat: Implement async cascade operations
- Add full async cascade delete support in QuerySet.async_delete()
- Support CASCADE, NULLIFY, PULL, and DENY rules
- Handle document collection and conversion for cascade operations
- Add support for pull_all operator in async_update()
- Update Document.async_delete() to use async GridFS deletion
- Add comprehensive test suite with 7 cascade operation tests
All async cascade operations now work identically to their sync counterparts,
maintaining full backward compatibility while providing async performance benefits.
* feat: Implement async context managers for mongoengine
- Add async_switch_db: temporarily switch database for documents
- Add async_switch_collection: temporarily switch collection name
- Add async_no_dereference: disable dereferencing for performance
- Handle both sync (_collection) and async (_async_collection) caching
- Add comprehensive tests with nested context managers and exception handling
- All 5 tests passing
This completes the async context managers component of Phase 4.

* feat: Implement async transaction support
- Add async_run_in_transaction context manager for atomic operations
- Support session_kwargs and transaction_kwargs customization
- Implement automatic commit with retry logic
- Handle transaction abort on exceptions
- Add comprehensive tests covering:
- Basic transaction commit
- Transaction rollback on error (skipped if no replica set)
- Nested documents in transactions
- Multi-collection transactions
- Transaction isolation
- Custom read/write concerns
- All tests passing (5 passed, 1 skipped)
This completes the async transaction support component of Phase 4.

* feat: Implement async aggregation framework support
- Add async_aggregate method for aggregation pipelines
- Add async_distinct method for distinct value queries
- Support all queryset filters, sorting, and limits in aggregation
- Handle embedded document field distinct queries
- Support async session management in aggregation
- Add comprehensive tests covering:
- Basic aggregation with grouping and sorting
- Aggregation with queryset filters
- Distinct queries on regular and embedded fields
- Complex aggregation with $lookup (joins)
- Aggregation with sort/limit from queryset
- Empty result handling
- All 8 tests passing
This completes the async aggregation framework component of Phase 4.

* docs: Update progress for completed aggregation framework implementation
* fix: Add hasattr check for _get_db_alias in ReferenceField
- Fix regression where EmbeddedDocument objects don't have _get_db_alias method
- Add proper check before calling is_async_connection()
- Ensures backward compatibility with existing sync tests
- All 170 document instance tests now pass
* docs: Comprehensive update of Phase 4 completion status
- Mark all core Phase 4 features as completed
- Update Success Criteria with accurate completion status
- Document 25+ async tests with 100% pass rate
- Confirm no regression in sync functionality (all existing tests pass)
- Mark non-critical features as deferred (values, explain, signals)
- Add detailed technical achievements and learnings
- Prepare for potential Phase 5 or upstream contribution
* docs: Complete Phase 4 documentation and project finalization
- Delete completed PROGRESS_ADVANCED.md
- Update PROGRESS.md with final project status and achievements
- Add Phase 4 implementation learnings to CLAUDE.md
- Document 79+ tests, 30+ async methods, 100% compatibility
- Add technical insights and future work guidance
- Project ready for production use and upstream contribution
