A test pins review and comment bounds: more than 50 line comments, or an empty comment, is refused and nothing is written #7087

submitReview in src/actions/pulls.ts refuses more than MAX_REVIEW_LINES (50) line comments with too_many_lines. addCommentThrough in src/actions/issues.ts refuses an all-whitespace body with empty_body. No test names either.

Done:

• [ ] A new test submits a review with 51 line comments through the API and gets the refusal. No review and no comment are stored.
• [ ] Exactly 50 succeeds.
• [ ] A comment of spaces and newlines is refused through the API and MCP alike, and the thread is unchanged.

If the test finds the behaviour wrong, fix the action in the same pull and say so. If the check fails in a test this pull does not touch, name it in the pull rather than widening the change.

Before pushing: bun x tsc --noEmit and the new test.
