The picker blocks on user input for however long they take. In that
window niri can destroy a dynamic workspace (its last window closed)
and renumber every later one down, so the pre-pick current["idx"] can
point at the wrong workspace by the time move-window-to-workspace
runs — restoring to the wrong place. The stashed window itself can
also have closed in the meantime, in which case the move/focus calls
would silently no-op. main() now re-reads workspaces/windows after
pick() returns, recomputes the current workspace, and confirms the
chosen window still exists before acting; each bails with a notify
and the documented exit code otherwise. Adds window_exists() as a
pure, tested helper alongside the existing pure functions.
Also: clarify the focus=false comment in niri/config.kdl (it read as
if focus=false caused the problem it actually prevents), and note in
the design doc's Out of scope section that the stash's index-1
pinning is per-output, so a second monitor would need its own
analysis of the Mod+1..9 offset.
Mod+M referenced an undeclared 'minimized' workspace, so it silently did
nothing. Declare it, add focus=false so focus does not follow the window
into the stash, and point Mod+Shift+M at the restore picker.
niri pins declared named workspaces to index 1 and will not move them, so
Mod+1..9 are offset by one.
Two tasks: window-restore.py + unit tests, then the niri config declaration,
bind rewiring and install.sh symlink. Script precedes config so Mod+Shift+M is
never wired to a missing script.
Plan code verified by extracting both blocks and running the test suite against
the script: 18/18 pass, and the step-2 failure mode is confirmed.

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.
