- outbox: delete_message/message_info now match the exact lane first
(a flat-lane delete/lookup with thread_id=None sees only frames with
no thread_id) and fall back to the message_id across all lanes only
when the exact lane matches nothing. Previously lane=None meant
'any lane' in the first pass, so a flat-lane delete also removed
same-id frames from threads (test expected 3 removed, got 4).
- http_server: the SSE live loop skipped queued frames when stop() set
sub.closed before the handler thread reached the loop (descheduled
under load between the initial hello/status writes and the loop).
The loop now drains frames queued before the close, so the
status{restarting} teardown broadcast always reaches the client
before EOF (test_disconnect_broadcasts_status_restarting was flaky
~70% under CPU load).
