test(compression): cover the attempt record of a rotating session-backed commit

#118580's regression test covers an in-place commit. A rotating commit
runs the same memory flush and then switches the agent to the child
session, so its record could lose the attempt's fields or name the child.
Drive both commit modes through a real AIAgent with a session database
and assert the record keeps this attempt's trigger, method, effect and
regions, and names the session the attempt started in. Both cases fail
without the telemetry hold around commit_memory_session.
