Review summary

Approved. The PR moves the remaining Mastodon-specific preview behavior into the ActivityPub object, matching the working pattern from erikcraddock.me.

Acceptance criteria coverage

Emits language-tagged ActivityPub content by using contents: [content, new LanguageString(content, "en")].
- Fedify serializes this as both content and contentMap, which should prevent Mastodon from offering translation on future delivered statuses.
Adds article image attachment metadata.
- The first markdown image is emitted as a Document attachment with absolute URL, media type, and alt/name.
Preserves existing Note/Article behavior.
- Existing content still serializes as content; tests now additionally assert contentMap.
Tests cover the new ActivityPub serialized output.
- Outbox test asserts article attachment metadata and contentMap for article/note objects.

Verification

npm run typecheck
npm test -- --run src/federation/__tests__/routes.test.ts
npm test
npm run build

Important follow-up gate

Do not close task task-2494df77 after merge alone. It should remain open until release/deploy and Chromium/Mastodon verification show the article card image and no unwanted Translate control for a newly delivered/refetched Mastodon status.

Blocking issues

None.
