Add BLE host transport selectable via DIP8 alongside UART.

Browse Source 
Master can speak the same framed protobuf protocol over NimBLE or UART; goTool gains -ble, ble-rtt, and ble-stream timing checks for ESP-NOW coexistence.

**Host UART vs BLE:** Nur einer aktiv (DIP8). Gleiches Framing (`0xAA`…`0xCC`) und dieselbe `cmd_queue`. BLE: NUS-ähnliche GATT-Char, Write=RX, Notify=TX. OTA und Dashboard (`gotool serve`) bleiben UART-only. Bei BLE-Host und aktivem Accel-Stream pusht `ble_stream` periodisch `BLE_STREAM_TICK` (8–16 ms) mit `esp_timestamp_us`.
