Description of changes:
Optimize AgentCoreMemorySessionManager by caching agent created_at timestamps to avoid unnecessary API calls during agent updates. Previously, update_agent() called read_agent() on every update to fetch the created_at timestamp, which triggered a list_events API call. Since AgentCore Memory is immutable and updates create new events, the original created_at must be preserved, but fetching it repeatedly was inefficient.
