### Added

- BLE Nordic UART Service (NUS) for app control via JSON protocol
- `ble` module (`src/ble.rs`): Command/Response types with serde, command handler, state snapshot builder, JSON serialization helpers — all `no_std`, no heap, unit-testable
- `ble_task`: async task advertising as "AirLED", serving NUS GATT service with chunked notifications
- Newline-delimited JSON protocol over BLE: externally-tagged command enums (`{"GetState":null}`, `{"SetBrightness":{"value":128}}`), flat `StateResponse` struct, plain `"ok\n"` / `"err:reason\n"` acks
- Auto-push state on BLE connect and on MSP flight mode change via `STATE_CHANGED` signal
- Chunked BLE notifications (20-byte MTU) for state responses (~250 bytes)
- MSP flight controller integration over UART1 (GPIO20 RX, GPIO21 TX, 115200 baud)
- `msp` module (`src/msp.rs`): MSPv1 frame builder, response parser state machine, BOXNAMES decoder, flight mode resolver — all `no_std`, no heap, fully unit-testable
- `msp_task`: async task polling MSP_STATUS at ~10 Hz, with BOXNAMES discovery at startup
