catalogue: add cloud.caesium.applaunch

[alanmur]

Adds App Launch (cloud.caesium.applaunch) to the Native OpenAction plugins section.

App Launch puts installed desktop applications on Stream Deck keys. You pick an app from a searchable list, the key shows its icon and name, and pressing the key launches it with gtk-launch. Icons can be full colour, white, black or a custom colour, and names follow the language you choose. Linux only.

• The plugin was written with an AI assistant (Claude), so ai_assisted is set. A full specification and test plan is in the repository at docs/spec2.md.

What does this provide over the alread existing Linux App Launcher Plugin from the OpenDeck Dev himself?

Also what happens on systems that don't have "gtk-launch" because they are KDE based for example.

This is just a duplicate of the existing plugin. Sure, it adds black and white versions of app images or the app name text, but users can already set those themselves.
