+ * Routes channel/thread renames through a second bot token (RENAMER_BOT)
+ * so renames don't consume the primary bot's per-channel 2/10min budget.
+ *
+ * The secondary bot must be invited to the guild with Manage Channels
+ * and Manage Threads.
+ *
+ * Not called directly from feature code — invoked by services/channelQueue.js
+ * so all channel ops continue to flow through the queue.
