Fixed
- Slash-command result cards now finalize through the extension's own snapshot timing instead of relying on core to treat hidden custom messages as in-place updates. The final slash snapshot and hidden persisted message are written before the last status-clear redraw, so live
/run,/chain, and/parallelcards update to their final state more reliably. - Added focused slash-command regression coverage for the success/error ordering around visible placeholder messages, hidden final messages, and the final status-clear redraw.
