[Bug]: macOS not open

### Pre-flight checklist

- [x] I searched [existing issues](https://github.com/AprilNEA/OpenLogi/issues?q=is%3Aissue) and this is not a duplicate.
- [x] I am on the [latest release](https://github.com/AprilNEA/OpenLogi/releases/latest) or a recent `master` build.
- [x] I quit **Logi Options+** before running OpenLogi (the two apps fight over HID++ access and only one can own a receiver at a time).

### Which part of OpenLogi?

GUI (desktop app)

### OpenLogi version

0.8.3

### Operating system

macOS

### OS version & architecture

macOS 14.7.1

### Device model

Mx master 4

### How is the device connected?

Bluetooth (direct, no receiver)

### Affected area(s)

- [ ] Device discovery / detection
- [ ] Button remapping
- [ ] DPI control
- [ ] SmartShift
- [ ] Per-application profiles
- [ ] Battery status
- [ ] Settings / configuration (TOML)
- [ ] Auto-update
- [ ] Menu bar / tray
- [x] Other

### What happened?

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.

### macOS permissions (if applicable)

- [x] OpenLogi has **Accessibility** permission (needed to remap buttons via the event tap).
- [x] OpenLogi has **Input Monitoring** permission (needed for Bluetooth-direct devices and capture).

Reproduce the macOS Bluetooth-direct path with `openlogi list`, then start from the `openlogi_device::inventory` and `openlogi_hid::transport` paths named in the logs. Done means OpenLogi launches and the MX Master 4 is detected without the reported Input Monitoring failure.
