chore: 1.2.0

Steam's autoscroll stops depending on -noverifyfiles: the patch is written at
the size and timestamp Steam recorded, so the client's own file check finds
nothing to repair and the flag survives whichever way Steam was started. An
installation patched by 1.1.0 is redone at the original size on the next apply.

Also picks up the launch paths that were never covered - shortcuts on the
desktop, Steam as a Flatpak, steam-native and steam-jupiter.
