Pull request overview

This PR updates the package-change workflow to use toast notifications during the preview phase and to improve error reporting when applying changes.

Changes:

• Add a “Previewing package changes” in-progress toast while computing dry-run previews.
• Skip opening the preview dialog when the dry-run indicates no solver side effects, and proceed directly to apply.
• Improve apply error toasts by showing a short first-line message with a “Show details” action.

In the error path where toastId is still empty, the code emits an error toast but does not dismiss previewAllNotification, which can leave the in-progress preview toast lingering alongside the error. Dismiss previewAllNotification in this branch as well (ideally via a shared cleanup/finally).

The three dry_run_preview calls are awaited sequentially, which increases latency compared to the previous behavior where the dialog loaded previews concurrently via Promise.all. Consider running these previews in parallel (e.g., await Promise.all([...])) and then using the results for has_side_effects checks / job data.
