[Bug]: macOS 26.6 (Intel) + MX Master 2s over 2.4G: Finder Forward/Back buttons stopped working in 0.6.25

### 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

0.6.25

### Operating system

macOS

### OS version & architecture

macOS Tahoe 26.6，Intel

### Device model

MX Master 2s

### How is the device connected?

Logi Bolt receiver

### Affected area(s)

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

### What happened?

With OpenLogi **0.6.24**, the **Forward** / **Back** side buttons on my MX Master 2s (connected via the 2.4G Unifying receiver) work correctly in Finder.

After upgrading to **0.6.25** (and later versions), these two buttons are **completely dead** in Finder — clicking them does nothing and no navigation is triggered.

### Steps to reproduce

1. Intel Mac running macOS 26.6
2. Connect MX Master 2s via the 2.4G (Unifying) receiver
3. Make sure Logi Options+ is fully quit
4. Install and run OpenLogi 0.6.24 → click Back/Forward side buttons in Finder → **works**
5. Upgrade to 0.6.25 → click the same side buttons in Finder → **does nothing**

### Diagnostics report

### `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 by reproducing the regression in Finder with an MX Master 2s over the Unifying receiver, comparing OpenLogi 0.6.24 and 0.6.25. Inspect the button-remapping event-tap path; no source file, test, diagnostics report, or logs are named. Done means Forward and Back trigger Finder navigation again on the affected setup.
