New Features

• SessionStore adapter: Full SessionStore support at parity with the TypeScript SDK. Includes a SessionStore protocol with 5 methods (append, load, list_sessions, delete, list_subkeys), InMemorySessionStore reference implementation, transcript mirroring via --session-mirror, session resume from store, and 9 new async store-backed helper functions (list_sessions_from_store, get_session_messages_from_store, fork_session_via_store, etc.). Also adds a 13-contract conformance test harness at claude_agent_sdk.testing.run_session_store_conformance for third-party adapter authors (#837)
• Reference SessionStore adapters: Three copy-in reference SessionStore adapters under examples/session_stores/ — S3 (JSONL part files, mirrors the TS S3 reference), Redis (RPUSH/LRANGE lists + zset index), and Postgres (asyncpg + jsonb rows). Not shipped in the wheel; users copy the file they need into their project (#842)
