### Description Adds Redis as a supported cache backend for LangGraph node-level caching, enabling distributed caching across multiple processes/servers. This implementation follows the same patterns as existing InMemoryCache and SqliteCache. ### Key changes - New RedisCache class implementing the BaseCache interface - Support for TTL-based expiration and batch operations - Worker-specific cache prefixes for parallel test isolation ### Dependencies - redis package (already included in dev dependencies) ### Test Plan - Unit tests: Added Redis cache tests covering basic operations, TTL, batch operations, and error handling - Integration tests: Redis cache integrated into existing LangGraph test suite, tested with all checkpointer combinations
