Refresh the panel/tray/settings screenshots, normalise "tray menu.png" to
tray-menu.png (drop the old "panel resorted.png"), and add a hero image plus a
Screenshots section (settings tabs) to linux/README.md.

Add Screenshots/ (panel + settings tabs: engines, input, general, benchmark,
about) for documentation, and pyrightconfig.json pointing the type checker at
the system dist-packages so it resolves PyGObject (gi).
