[Feature]: Smart Zoom support

[taylor325]

Pre-flight checklist

• I searched existing issues and the Roadmap, and this isn't already tracked.

Problem / motivation

I want to completely ditch Logi Options+ because it is buggy and bloated with telemetry. OpenLogi is the perfect lightweight alternative, but it is currently missing one crucial feature that keeps me from switching: Smart Zoom (the native macOS double-tap to zoom functionality).

Without this feature, it is difficult to fully transition away from the official Logitech software, as Smart Zoom is one of the most useful daily shortcuts on macOS. If this gets added, I will immediately switch over to OpenLogi as my primary driver.

Proposed solution

Add a dedicated "Smart zoom" action to the button mapping list (as shown in the attached screenshot from the official Logitech software).

It should allow users to easily assign the native macOS Smart Zoom feature to any customizable mouse button. When the assigned button is pressed, it should trigger the exact same system action as a double-tap on a Magic Mouse or trackpad.
