PR #180 review (BLOCK) found that moving delivery out of the scan left two problems: - An alert waited for deliver's own tick, about one interval. It is now flushed as soon as it is handed over, and on each tick after that while it is still pending. - On ctx end deliver returned without draining, so an alert handed over just before shutdown was lost even with a healthy ntfy. Watch now closes the handoff channel, and deliver drains it and flushes once more (bounded by shutdownFlushTimeout) before Watch returns. The review also showed the tests didn't cover the handoff. The new tests are each flip-tested red: - the lifetime test uses a notifier slower than the interval, so a blocking handoff fails it - the overflow-accounting test uses a slow notifier - a join test checks that Notify is no longer running when Watch returns - a shutdown-flush test, and a prompt-delivery test Refs #164 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
