Accel/tap use fire-and-forget ESP-NOW with a 10 ms FreeRTOS-safe cadence, OTA recovers from seq gaps and auto-reboots after success, and bootloader app rollback confirms after a stable boot.

Allow the same staged firmware upload path on BLE as UART, fix distribute stack/event-group crashes, and recover sticky slave OTA sessions instead of failing with err=4.

Split ESP-NOW into core/master/slave modules, block non-OTA UART traffic during updates, and hold the host serial port exclusively so dashboard polling cannot interleave with firmware uploads.

Default brightness is ~5%; UART blink mode and green/red pulses mark OTA success or failure. Failed UART uploads skip ESP-NOW distribution.

Expose OTA_SLAVE_PROGRESS on the master, track per-slave state during
distribution, run ESP-NOW OTA in a background task so the host can poll
while slaves update, and show master/slave progress in the dashboard
with table layout and faster WebSocket refresh during uploads.

After UART OTA the master reads the staged partition in 4 KiB blocks (200 B ESP-NOW chunks), waits for per-slave block ACKs, and fixes the final partial block. Slaves reuse ota_uart; send pacing and logging improve reliability.
