Slaves push BMA456 samples at 16ms when enabled; the master caches per
client and exposes ACCEL_SNAPSHOT and ACCEL_STREAM over UART. goTool adds
dashboard stream controls, HTTP accel-stream routes, and an external
WebSocket API with per-connection receive/interval and slave stream commands.

Expose MessageType 24 with protobuf response (success, x, y, z in raw LSB),
firmware handler with mutex-safe I2C read, goTool `accel` CLI, and docs.

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

Stop the main-loop digit demo so host-driven display persists; expose
clear/progress/digit modes with RGB and intensity via protobuf and goTool.

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.

Firmware buffers 200-byte chunks into 4 KiB blocks for esp_ota_write; goTool
uploads with per-block ACK flow control and larger UART buffers to avoid stalls.

Register slaves from recv src_addr instead of protobuf mac bytes, add
ESPNOW_UNICAST_TEST for path verification, restore unicast deadzone, and
expose unicast-test in goTool.

Filter BMA456 logs by configurable LSB threshold; master can set deadzone
for local sensor or slaves using ACCEL_DEADZONE (UART) and ESP-NOW broadcast
until unicast delivery is restored.

Add esp_now_messages.proto with EspNowMessage types, encode/decode helpers,
and Makefile targets to regenerate firmware and UART schemas together.

Centralize command dispatch over a FreeRTOS queue so UART and future
ESP-NOW transports can register handlers; implement the protobuf VERSION
command with framed nanopb responses including build git hash.
