Custom Chat Message Indicators

The <dyad-status> tag in chat messages renders as a collapsible status indicator box. Use it for system messages like compaction notifications:

<dyad-status title="My Title" state="finished">
Content here
</dyad-status>

Valid states: "finished", "in-progress", "aborted"

• Renderer unit tests that import DyadMarkdownParser should mock ../preview_panel/FileEditor; otherwise the DyadWrite import initializes Monaco and Happy DOM may try to fetch cdn.jsdelivr.net, causing offline ENOTFOUND failures.
