"""Regression tests for AIAgent.commit_memory_session.
Issue #22394: commit_memory_session was calling MemoryManager.on_session_end
but never ContextEngine.on_session_end. Context engines that accumulate
per-session state (LCM-style DAGs, summary stores) leaked that state from a
rotated-out session into whatever continued under the same compressor
instance.
