Add Monologue as a default app (#13449)

Monologue is Omarchy's own webcam recorder: pick a camera and microphone
once, press Space to record, and stop straight into a built-in editor
to split, trim and remove clips before saving an MP4.

Ship it in the base packages alongside Omacut, include it in the
preinstall restore/remove lists, and describe it in the manual. A
migration installs it on existing machines unless the user removed the
preinstalls.
