Move all communication from USB to BLE. The device now advertises as "Claude Controller" and acts as both a BLE HID keyboard (for touch gestures) and a GATT data server (for usage updates from the daemon). - Add NimBLE-Arduino BLE module with custom GATT service + HID keyboard - Add third screen (Bluetooth) with connection status, MAC, reset button - Rewrite daemon in bash using bluetoothctl/busctl for BLE GATT writes - Add screenshot capture via LVGL snapshot over serial - Remove TinyUSB mode — normal pio upload works again - Update README with BLE architecture, screenshots, gesture docs Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
