agent.await and agent.spawn{await:true} now return immediately when
children are still running: the session closes, runAgent registers a
wake signal in agent_run.await_wake and waits with waitForFact without
holding an io/agent worker slot. A child that settles (terminal or
waiting) signals the parent's registered fact, so the parent resumes at
once instead of polling; the suspended call replays and the child
report becomes the tool result. agent.spawn is registered replay-safe;
a suspended spawn is recorded as failed in the ledger so the replay
re-runs it against the same child.
Migration 0037 also adds the admin_recovery_code, admin_passkey and
webauthn_challenge tables used by the account work.
E11 asserts the parent is suspended with no run held by any worker
while it waits, and covers spawn{await:true} end to end.
