[Bug]: Rename action not working

### 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.

### `openlogi list` output

```text

```

### Logs

```shell

```

### macOS permissions (if applicable)

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

Start in the desktop GUI code that builds the device context menu and handles the “Rename...” action; no file or test is named in the report. Reproduce on Windows 25H2 with OpenLogi 0.8.3, then verify that selecting Rename opens name input and that the new name is saved and displayed for the device.
