Add Omarchy shell plugin for the Stream Deck

QML bar widget + popout panel (dev.woodard.streamdeck) that drives
streamdeck-ctl: key grid shaped by the connected model, per-key editor,
brightness slider, and daemon controls. Themed via qs.Commons.

Makefile gains build-ctl, install-ctl, install-plugin, validate-plugin
and uninstall-plugin targets.
