#23)

- Add Time-To-Live (TTL) functionality to Redis store implementation TTL using Redis's native TTL functionality
- Update dependency to langgraph ^0.3.0 with proper import handling for create_react_agent and fix various type errors to ensure linting sanity.
- Added null checks for connection_args to satisfy mypy type checking.
- Implemented the URL environment variable handling directly in our code.

  Adds proper Redis client identification using SET_CLIENT_INFO for both synchronous and asynchronous clients. Includes graceful fallback to echo when the command is not
  available and comprehensive tests for both checkpoint and store components.

…#13)

  Add cleanup logic to AsyncShallowRedisSaver and ShallowRedisSaver to delete
  old blobs and writes when storing new checkpoints. This prevents memory bloat
  when using shallow savers, which should only keep the latest checkpoint state.
  Add comprehensive test to verify the fix works correctly.

  Update previously skipped tests to work without external dependencies:
  - Replace test_batch_order with a functional test of batch operations
  - Implement memory_persistence test using sequential store connections
  - Convert LLM-dependent tests to use mock agents instead of real OpenAI
  - Fix root_graph_checkpoint tests to use proper configuration format
  - Add proper cleanup to ShallowRedisSaver implementations

  All tests now run successfully without API keys or special setup.

  - Add transaction handling to AsyncRedisSaver.aput and aput_writes methods
  - Add transaction handling to AsyncShallowRedisSaver.aput method
  - Fix typing issue in shallow.py
  - Add comprehensive tests for interruption handling
  - Ensure atomic operations in Redis using pipeline with transaction=True
  - Proper handling of asyncio.CancelledError during interruptions
