 * Auto-inject Telegram forum topic thread ID when the message tool targets

 * pattern so media, buttons, and other tool-sent messages land in the correct
 * topic instead of the General Topic.
 *
 * Unlike Slack, we do not gate on `replyToMode` here: Telegram forum topics
 * are persistent sub-channels (not ephemeral reply threads), so auto-injection
 * should always apply when the target chat matches.
