Keep rollback active until the directory state is stable.

If the second mv succeeds and a signal arrives before Line 34 clears the trap, dest already exists. Line 30 then moves old inside the new dest directory instead of restoring the original top-level directory. The failure path also clears the trap at Line 38 before moving old back, so a signal in that interval can leave dest absent.

Make the handler remove an installed dest only when old still exists, and clear the trap only after rollback completes.

Proposed fix 
-        trap "mv \"$old\" \"$dest\" 2>/dev/null || true; exit 1" INT TERM HUP
+        trap 'if [ -d "$old" ]; then
+                  if [ -e "$dest" ]; then rm -rf -- "$dest" || exit 1; fi
+                  mv -- "$old" "$dest" || exit 1
+              fi
+              exit 1' INT TERM HUP
...
-        trap - INT TERM HUP
         echo "Error: Failed to install $label; restoring previous data"
         if [ -d "$old" ]; then
             mv "$old" "$dest"
         fi
+        trap - INT TERM HUP

In `@deployments/cli/community/restore-airgapped.sh` at line 30, Update the
rollback trap in the restore script so it removes the installed dest only when
old still exists, then moves old back to dest; keep the trap active through the
rollback and clear it only after the rollback completes, including the failure
path around the second mv.
