fix: reduce loop delay to 10ms so __loopHook processes RPCs
...
Validate and Test / validate-patches (push) Failing after 12s
Background thread stack (500 bytes) overflows after ~50 draw_frame
calls. __loopHook (called after loop() returns) is the fallback.
With delay(1000), it ran once per second — too slow.
Reducing to delay(10) keeps RPC processing responsive.

fix: no reconnect storm on send failure, reduce refresh to 1 FPS
...
Validate and Test / validate-patches (push) Failing after 13s
- 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

fix: add Bridge.run() to loop() so MCU processes incoming RPCs
...
Validate and Test / validate-patches (push) Failing after 13s
Without Bridge.run() in loop(), the MCU never reads incoming
draw_frame requests from the router. First frame goes through
during setup handshake, but subsequent frames fill the router's
send buffer and the viz stalls.

fix: robust router send with auto-reconnect, 10ms timeout
...
Validate and Test / validate-patches (push) Failing after 13s
- try_send() helper: reconnect on send failure
- 10ms socket timeout instead of 300ms (stalls poll loop)
- Refresh path also uses try_send
- Remove committed library bloat from repo (add .gitignore)

refactor: rename sketch to sketch.ino, add flash-sketch recipe
...
Validate and Test / validate-patches (push) Failing after 12s
- Permanent rename: led-matrix-bridge.ino → sketch.ino (Arduino CLI convention)
- Add just flash-sketch recipe for compiling/flashing MCU via board's arduino-cli
- Run via post-merge hooks for auto-deploy
