zeekay d36da09318 feat(memory): Add multi-backend memory system with LanceDB, KuzuDB, and InfinityDB support ...

- Implemented pluggable backend architecture with BackendRegistry
- Added support for three database backends:
  - LanceDB: Vector database with embeddings and SQL-like queries
  - KuzuDB: Graph database for relationship-based memory storage
  - InfinityDB: High-performance vector database
  - Local files: Simple JSON storage (default)

- Created clean accessor syntax for backend selection:
  - Dictionary syntax: memory['backend']
  - Attribute syntax: memory.backend
  - Context manager: async with memory.use('backend')

- Added backend-specific features:
  - Vector similarity search (LanceDB, InfinityDB)
  - Graph relationships and traversal (KuzuDB)
  - Markdown import support across all backends
  - Capability-based backend selection

- Fixed compatibility issues:
  - Resolved async/sync method signatures
  - Fixed DataFrame operations (pandas vs polars)
  - Added proper JSON parsing for metadata fields
  - Implemented missing base class methods

- Added comprehensive test coverage and examples
- Created unified memory interface in memory.py
- All tests passing for available backends
