feat: add web asset rebuilding to update command and consolidate post-restart messages

- Detect web/src/** changes and trigger frontend rebuild after updates
- Add buildWebAssets flag to RestartContext and needsWebBuild to UpdateCheckResult
- Consolidate post-restart progress into single editable message
- Delete progress message after completion, show only final result
