Description

### 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

0.6.16

### Operating system

macOS

### OS version & architecture

macOS 26.5.1

### Device model

MX Master 3

### How is the device connected?

Other / not sure

### Affected area(s)

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

### What happened?

My mouse keeps disconnecting, so when my machine eventually goes to sleep my scrolling doesn't work as expected anymore.

Also, the openlogi CLI wasn't installed with Homebrew when I installed the cask. I thought it was supposed to install alongside eachother.

I have tried going back multiple versions, but to no avail. I have tried both installing using Homebrew and directly from GitHub releases.

My device is using the Unify receiver.

My first initial connection was excellent, but when I came back to my machine, it didn't connect. And when I "force" it to connect by readding it, it disconnects after a few seconds.

### Steps to reproduce

1. Leave machine unattended (wait for sleep)
2. Try to use mouse with config
3. Doesn't work…
4. "Force" reconnecting by readding
5. Disconnects after a few seconds.

Research direction

Start with OpenLogi's device discovery and connection handling for macOS Unifying receivers, using the diagnostics report for the MX Master 3 as the reproduction context. Reproduce sleep, reconnect, and re-add behavior with the receiver, then verify the device remains online and usable after wake without forced re-adding.
