Code Review Enhancements & GitHub PR Integration

[backnotprop]

Overview

/plannotator-review <pr-link> works today.

Extend the PR review mode with richer GitHub integration — contextual PR information, issue linking, direct PR actions, and multi-PR navigation.

Currently PR review shows the diff and supports annotations, but lacks the surrounding context that makes a review actionable: PR metadata, comments, merge status, linked issues, and the ability to act on the PR directly from the UI.

---

1. PR Context Panel

Display rich PR metadata in the review UI — a panel or tab alongside annotations.

• PR summary — title, description, author, branch info (metadata already fetched, just not displayed)
• PR comments — conversation thread from GitHub
• Merge status — checks passing/failing, review approvals, merge conflicts
• Linked issues — issues referenced in the PR description or commits

Open questions

• Tab within the annotation panel, sidebar section, or collapsible area? → Icon tabs inline in the panel header

2. Issue Attachment in Feedback

Let reviewers reference GitHub issues in their annotations/feedback, so when feedback is sent back to the agent or posted as a PR comment, it links to relevant issues for context.

• Attach existing GitHub issues to annotations
• Issue references included in exported feedback markdown

3. PR Actions

Actions that execute directly against the GitHub PR from the review UI.

• Approve PR — posts a GitHub approval review (not just local LGTM)
• Post feedback as PR comment — annotations become a review comment on GitHub
• Squash & merge — after approval, optionally merge the PR

Open questions

• Direct automation (Plannotator calls gh itself) vs agent-mediated (send "merge this PR" as feedback to the agent) vs both as user-configurable options?
• Should squash & merge be a separate explicit action, or offered as a follow-up after approval?

4. PR Navigation

• Browse open PRs — switch between PRs without restarting (like the diff-type switcher for local reviews)
• Navigate to linked issues — from the context panel, open referenced issues
