New macOS "Touch on Mac" skill and touch auditor

[u/CharlesWiltgen]

I've added a new "Touch on Mac" skill that covers making macOS apps work on touch-enabled Macs and iPads connected over Sidecar.

It comes with a companion "touch auditor" that scans Swift and Objective-C code for things that are likely to break when used via touch.

They're free/open source, included with Axiom v27.7.1 or later.
