[Device]: MX Ergo S, unsupported features

### Pre-flight checklist

- [x] I quit **Logi Options+** before testing.
- [x] I searched existing issues for my device.

### Device model

MX Ergo S

### Connection

Bluetooth (direct, no receiver)

### What's the problem?

Requesting support for a device not yet supported

### `openlogi list` output

```text
installed via brew but openlogi command doesn't seem to work, cli app isn't there
```

### `openlogi diag features` output

```text
installed via brew but openlogi command doesn't seem to work, cli app isn't there
```

### Details

Device is recognized automatically. Gestures works but when OpenLogi is running DPI button and horizontal scrolling doesn't work.

Start by reproducing the MX Ergo S behavior over Bluetooth and investigate the openlogi list and openlogi diag features entry points, which the report says are unavailable after the Homebrew install. Done means the device retains working gestures while the DPI button and horizontal scrolling also work when OpenLogi is running.
