Release v1.41.0 adds MultiAgentPlugin for Swarm and Graph orchestrators, bumps Starlette to 1.x, and introduces TTL support in Bedrock caches.

Why it matters: Plan migration testing for the new MultiAgentPlugin and Starlette 1.x upgrade; evaluate enabling TTL on auto‑injected Bedrock cache points as a performance tweak.
