### Details

The device is detected correctly and its image is displayed in OpenLogi, but only the DPI setting is available and working. None of the three- or four-finger gestures (configed with Options+) work, I guess they need Options+ runtime.

In Logi Options+, it shows these config: (images)

Start by reproducing the supplied `openlogi list` and `openlogi diag features` outputs for the Casa Touch, then compare its feature IDs with the detected MX Anywhere 3. Trace the existing device-support entry points for the working DPI behavior and identify how the configured three- and four-finger gestures should be exposed; done means those gestures work without Logi Options+.
