feat(web): merge the comment and review buttons into one composer

[Bil0000]

The pull request detail panel now has one floating composer for comments and reviews, available from Summary, Timeline, and Code. Its Comment / Review toggle preserves separate drafts and opens on pending review work. Review mode offers Comment, Approve, and Request changes through a verdict selector and one Submit review button, filtered by host capabilities and permissions.

Both textareas use the same default size and three rows, removing the 4 px height jump between empty modes. Closing the popover preserves comment drafts and in-flight submission guards. Review mode restores bulk discard for pending line comments, including drafts whose files disappeared; discard is disabled while a review is submitting. Existing close/reopen comment actions and provider validation remain in place.

Verification: Targeted lint, 32 existing detail-panel and review-store tests, and web typecheck passed. In the shared dev client against the real GitHub PR, checked verdict selection, submit eligibility, draft preservation, and matching composer heights at desktop and narrow widths in dark and light themes. Submitted the follow-up status as a Comment review through the actual client and GitHub provider; confirmed it appeared on GitHub and the composer closed on success. Approve and Request changes selection/eligibility were checked without posting those verdicts. A locally seeded stale line draft verified bulk discard without losing the summary. Holding an actual outgoing Comment review request verified disabled discard during submission; releasing it posted through GitHub, re-enabled discard, and preserved a local draft added after the submitted snapshot.

Before: separate comment and review controls.

After: one composer with verdict selection and preserved drafts.

Initial implementation by Bil0000 with Claude Opus 5 in T3 Code through Claude Code. Follow-up by Maria with gpt-6-astra in T3 Code through Codex.

📝 Walkthrough

Walkthrough

The pull request detail panel now uses one composer for comments and reviews. Draft review summaries and pending line comments select review mode. The code tab removes its floating review overlay.

Changes

Pull request composer

Layer / File(s)	Summary
Remove code-tab review overlay apps/web/src/components/pullRequest/PullRequestCodeTab.tsx	The code tab removes the overlay, related state, icons, verdict handling, and wrapper logic.
Add comment and review forms apps/web/src/components/pullRequest/PullRequestCommentForm.tsx, apps/web/src/components/pullRequest/PullRequestCommentComposer.tsx, apps/web/src/components/pullRequest/PullRequestReviewForm.tsx	The old comment composer is deleted. The new comment form handles comment submission and permitted close or reopen actions. The review form uses a shared textarea reference, a verdict selector, and one submit button.
Wire the unified composer apps/web/src/components/pullRequest/PullRequestComposer.tsx, apps/web/src/components/pullRequest/PullRequestDetailPanel.tsx, apps/web/src/components/ui/popover.tsx	The composer selects review mode when review work exists and preserves both forms across toggles. The detail panel renders it and refreshes detail data after review submission. The popover can keep content mounted.

Merge Risk: ⚪ Minimal · up to ac09a

The consolidated comment/review composer and its discard control behave safely even if a user discards a draft while a review submission is still in flight, since the in-flight request already holds its own snapshot of the submitted text and comments. No unresolved correctness or data-integrity issue remains from this review.

Pushed the requested follow-up in 31f0c31: matching composer sizing and a review verdict selector with one submit button. Targeted lint, 32 existing tests, and the web typecheck passed. This review comment is submitted through the updated T3 composer to verify the real GitHub submission path. CI and final review are still in progress.

The follow-up preserves drafts across dismissal and restores pending-comment discard. The final review fix disables discard while submission is in flight. Targeted lint and web typecheck passed.
