Mod+M and Mod+Shift+M reference a "minimized" named workspace that was never
declared, so both binds have always been silent no-ops. Design covers the
declaration plus a wofi restore picker.
Constraints verified against niri 26.04 in a nested instance: undeclared named
workspaces are no-ops, declared ones are pinned to index 1 and cannot be moved
(hence the +1 offset on Mod+1..9), and focus=false is required or focus follows
the window into the stash.
