## What
- **Markdown comments**: admin comments on the integration board now
render as markdown (`react-markdown` + `remark-gfm`) instead of plain
text. Links open in a new tab; blockquotes, lists and bold are styled.
Comments are admin-only (set via CLI), so the content is trusted.
- **`in_progress` status**: new status, visible to everyone and votable
like `approved`, with an optional public comment. Lets the admin signal
an integration is actively being built.
- **`integration-requests:review` rework**:
- Any decision can now move a request to any status (approve / in
progress / reject / not doable), not just the pending ones.
- New `--all` flag prints the full list with a `#` column so the admin
can pick a request by number and change its status.
- `not doable` requires a comment; `in progress` allows an optional one;
approve/reject clears any stale public comment.
## New dependencies
- `react-markdown`, `remark-gfm` (approved with the author).
## Tests
- 24 feature tests passing, incl. `--all` status change, `in_progress`
visibility + voting, and updated review-command option sets.
- Frontend vitest covering markdown rendering (link + blockquote).
