v0.7.9

Settings open in their own window, quickly, and come back as you left them; the feed's settings, backup & restore and icons are there too. Text files open in the launcher's own editor, also Linux's, and Files has a new look with a new-file action. New coding agents: Oh My Pi, Ori, Muse Code and Kimi. Terminals no longer flicker when the keyboard opens, and themes from the catalog show their screenshot.
