[Bug]: Action ring application opens the web browser instead of the app

### 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?

Not sure

### OpenLogi version

0.8.3

### Operating system

Linux

### OS version & architecture

ArchLinux

### Device model

MX Master 3S+ Logi Bolt receiver

### How is the device connected?

Logi Bolt 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?

When I select an application from the picker and launch it, the application does not start.
Instead, the web browser opens with the name of the selected application in the address bar.

### Steps to reproduce

1. I select the application—for example, Dolphin—in OpenLogi Settings.

2. I launch the application

3. The application does not start.
Instead, the web browser opens with the name of the selected application in the address bar.

### Diagnostics report

```markdown

```

### `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).

Reproduce the issue on Linux/Arch with Dolphin selected in OpenLogi Settings, then trace the action ring's application-picker launch path. Done means launching a selected application opens that application instead of the web browser.
