fix: pr +review now posts a journal comment alongside the formal review

The GitLink API has two separate systems for PR feedback:
- POST /pulls/:id/reviews creates a formal review (approve/reject/comment)
  that only appears in the "Reviews" panel
- POST /issues/:issueID/journals creates a comment visible in the main
  PR conversation tab

Previously, `pr +review` only called the reviews API, so the review
content was invisible to the contributor in the main PR conversation.
Now it also posts a journal summary so the review is visible where
contributors expect to see it.
