Subject: [PATCH] fix: no reconnect storm on send failure, reduce refresh to 1
 FPS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- try_send: don't reconnect on failure, just skip and retry next cycle
- Background refresh: 5 FPS → 1 FPS to reduce router serial load
- Revert Bridge.run() - RouterBridge uses Zephyr RTOS thread
