This release addresses critical issues with multi-turn tool flows and adds durable submissions for Think. Key changes include removing the default aggressive message pruning that was breaking multi-turn conversations, wrapping RPC turns in chat recovery fibers for partial output recovery, and adding `submitMessages()` for server-driven turns with idempotent retries and cancellation support.
