A reviewed-pull post on home says the verdict and the reviewer's first sentence #6468

Part 2 of #5823. The pull.reviewed event's payload already carries state and body (see reviewPull in src/actions/pulls.ts). Today src/feed/items.ts ignores them and posts reviewed a pull request: <title>.

Done:

• [ ] The pull.reviewed case in src/feed/items.ts uses reviewWords from src/feed/review_words.ts and falls back to today's words when that returns undefined.
• [ ] Folded posts (#5808, one post per pull) keep their folded words. Only a post that stands alone changes.
• [ ] test/feed-review-verdict.test.ts submits one approval and one changes-requested review on two pulls through the review action, then reads / as the owner and finds both lines, escaped. A line comment still reads reviewed a pull request.

Files: src/feed/items.ts, test/feed-review-verdict.test.ts

Already done on main in 0e2eaaf4 (#6459): reviewedPost and firstSentence in src/feed/items.ts word a review post as approved <title> or asked for changes on <title>: <first sentence>, with no colon for an empty body. They read the verdict from the review that payload.reviewId names, and test/feed-reviewed.test.ts covers it. All three crew pulls for #6467 (#6545, #6565, #6567) declined for this reason. Closing as done; #6469 (the ranking) is not covered and stays open.

Dropped: the forge would not close this as done with my note, and nothing is left to build. 0e2eaaf4 on main does it, as the comment above says.
