v0.3.19

What's new

• Home row keys: turn them on under Settings → Picker and A S D F G J K L ; pick the first nine windows, alongside 1-9.
• Panel width: a new slider under Settings → Picker → Sizing sets the picker's width separately from thumbnail size.
• With Stage Manager on, windows of apps that aren't on stage stay in the picker instead of showing as windowless.

Thanks to @gianito for the panel-width idea and @Ferezoz for the Stage Manager fix.
