Two fixes found reviewing the paths the acceptance suite couldn't cover.
Show-while-shown-elsewhere used activate_window, which sets
active_monitor_idx and so dragged *focus* to whichever output the window
was parked on. A scratchpad should come to you: if the window is on
another monitor, remove and re-add it floating on the active workspace;
if it is already on the active monitor, focus in place as before.
add_removed_tile_floating dropped the RemovedTile on both of its early
returns (NoOutputs, monitor-not-found), destroying the window while its
client was still alive and leaving it wedged with no surface anywhere.
Both were unreachable via scratchpad_show's guards, but it is a
window-loss footgun for the next caller. It now returns
Result<(), RemovedTile<W>> so callers can stash the tile instead.
Adds two layout tests (they simulate outputs, so multi-monitor is
covered without a second physical display) and corrects the acceptance
suite's test-8 skip message, which claimed the code used active_output
— it never did; it uses active_workspace.
cargo test --lib scratchpad: 10/10. acceptance.py: 8 passed, 0 failed.
