/**
 * v1.2 §4.5 — Owner-only gate (default ON for fresh installs; OFF for
 * v1.1.0 upgrades to preserve v1.0.2 channel-ACL-only behavior — the
 * migration writes `owner_only: false` explicitly so the resolver never
 * has to guess).
 *
 * The bot processes a message iff
 *   `message.author.id === user.yaml.messenger_user_id`.
 * Other senders in the same channel are silently ignored. Each
 * unrecognized sender gets *one* ephemeral notice per cooldown window so
 * the channel does not flood — every subsequent message from the same
 * (guild, sender) pair is fully silent.
 *
 * v1.0.2 was wrong-by-omission: it removed the author-guard because the
 * *channel name* at the time was user-id based, so the bot could not
 * tell which user's channel it was looking at — disambiguation was
 * impossible without the channel mapping that landed in v0.8.0
 * (`command-<handle>` / `works-<handle>`). With channel recognition
 * solved, the owner-id check becomes both feasible and the right policy
 * for a personal Chief bot. v1.2 restores it; existing installs keep
 * v1.0.2 behavior unless they opt in.
