 DM the bot directly or @mention it in a channel — it should respond!

-> - `groupPolicy`: `"mention"` (default — respond only when @mentioned), `"open"` (respond to all channel messages), or `"allowlist"` (restrict to specific channels).
+> - `groupPolicy`: `"mention"` (default — respond only when @mentioned), `"open"` (respond to all channel messages), or `"allowlist"` (restrict to specific channels via `groupAllowFrom`).
+> - `groupAllowFrom`: channel IDs the bot may respond in when `groupPolicy` is `"allowlist"`.
+> - `groupRequireMention`: when `true` and `groupPolicy` is `"allowlist"`, the bot only replies to channels in `groupAllowFrom` **and** only when @mentioned (instead of every message). No effect for `"mention"`/`"open"`. Use this to scope the bot to approved channels while keeping mention-only behavior.
