feat: route cron output via reviewer bot in paired rooms

In paired rooms, cron output was posted by the owner bot. Since the
owner can't respond to its own messages, the cron report just sat
there with no follow-up action.

Now cron output in paired rooms is posted via the reviewer bot. The
owner picks it up as a peer request, analyzes the report, and acts
on it (e.g., fixing Sentry errors). The normal paired review loop
then kicks in to verify the fix.
