[Device]: Mx Master

### Pre-flight checklist

- [x] I quit **Logi Options+** before testing.
- [x] I searched existing issues for my device.

### Device model

Mx Master

### Connection

Bluetooth (direct, no receiver)

### What's the problem?

Requesting support for a device not yet supported

### `openlogi list` output

```text
franciscodionisio@Franciscos-MacBook-Pro OpenLogi % openlogi list
No Logitech HID++ devices or webcams found.

Notes:
- On macOS, quit Logi Options+ first — both apps fight over HID++ access.
- A Bluetooth-direct mouse (e.g. Lift, Signature) needs Input Monitoring permission: System Settings → Privacy & Security → Input Monitoring.
- hidpp 0.2 only recognises Logi Bolt receivers (PID 0xC548); other receivers (Unifying) aren't surfaced yet.
```

### `openlogi diag features` output

no online HID++ devices found
```

### Details

I have the code to add support for this mouse (my mouse) which i have tested and it works flawlessly. Just like Mx Master 2s, just make it recognize the mouse.

Start by reviewing the existing MX Master 2S support and the HID++ device-identification path. Run `openlogi list` and `openlogi diag features` with Logi Options+ quit and the required macOS permission; done means the MX Master is recognized and its supported features are available like the MX Master 2S.
