+/**
+ * pi-channels — Config from pi SettingsManager.
+ *
+ * Reads the "pi-channels" key from settings via SettingsManager,
+ * which merges global (~/.pi/agent/settings.json) and project
+ * (.pi/settings.json) configs automatically.
+ *
+ * Example settings.json:
+ * {
+ *   "pi-channels": {
+ *     "adapters": {
+ *       "telegram": {
+ *         "type": "telegram",
+ *         "botToken": "your-telegram-bot-token"
+ *       },
+ *       "slack": {
+ *         "type": "slack"
+ *       }
+ *     },
+ *     "slack": {
+ *       "appToken": "xapp-...",
+ *       "botToken": "xoxb-..."
+ *     },
+ *     "routes": {
+ *       "ops": { "adapter": "telegram", "recipient": "-100987654321" }
+ *     }
+ *   }
+ * }
