feat: show multi-PR review status

[neversettle17-101]

Summary

• update the Reviews tab to render PR-scoped review state from reviews
• show per-PR statuses for needed, running, changes-requested, up-to-date, and ineligible reviews
• use each review row's latestRun for harness/terminal metadata when needed
• keep one session-level Run needed reviews action and one shared Open terminal action for the reviewer terminal

Tests

• cd frontend && npm run typecheck
• cd frontend && npm test -- SessionInspector

AO review — feat: show multi-PR review status

Verdict: Approve (ready to merge; only minor nits).

This is a clean frontend follow-up to the multi-PR backend change. ReviewsView now renders the new PRReviewState[] from the API: a single reviewer header card (harness + PR count + run/terminal actions) over a per-PR list of ReviewStateCards driven by the server-computed status enum (needs_review/running/up_to_date/changes_requested/ineligible). The latestReview/client-side verdict-derivation logic is correctly removed in favor of the backend's status, the refetch poll keeps running while any PR is running, and the trigger onSuccess opens the reviewer terminal only when a run was actually started.

Verified locally: tsc --noEmit clean and vitest run SessionInspector.test.tsx → 10/10 pass. Test coverage for the multi-PR rows and the reuse-notice path is good.

No blocking issues. A few nits below.

Nits (non-blocking)

• Pluralization: the header badge renders {reviewStates.length} PRs, so a single-PR session shows "1 PRs". Consider pluralizing.
• Status derivation for the header harness now picks the first reviewState with a latestRun (PR-number order) rather than the most-recent run as before. Fine in practice since the harness is session-wide, but it's a slight behavior change worth a comment.
• Styling consistency: ReviewStateCard mixes the existing BEM reviewer-card__* classes with Tailwind utilities (mt-2, opacity-70, arbitrary text-[10.5px]). Matches some existing usage but the fractional-pixel arbitrary value is unusual — a shared token/class would read cleaner per the design-system guidance.

{reviewStates.length} PRs renders "1 PRs" for a single-PR session. Consider pluralizing (e.g. ${n} PR${n === 1 ? "" : "s"}).

Header harness now derives from the first reviewState with a latestRun (PR-number order) rather than the most-recent run as the old latestReview() did. Harmless since harness is session-wide, but worth a brief comment so the change of intent is clear.

Arbitrary text-[10.5px] (fractional px) mixed with the BEM reviewer-card__* classes. Minor, but a shared token/utility would be more consistent with the design system.

AO re-review — feat: show multi-PR review status (frontend)

Verdict: Approve (clean redesign; prior nits addressed, only trivia left).

The Reviews tab now renders a single "review session" card with a per-PR summary list (ReviewStateRow) plus an aggregate verdict badge, driven entirely by the backend's PRReviewState enum. Nicely done:

• My earlier 1 PRs pluralization nit is gone — the count chip was replaced by the aggregate verdict / session header.
• Client-side verdict derivation stays removed; reviewVerdict/sessionReviewVerdict map the server status straight through.
• runDisabled correctly blocks re-triggering while any PR is running or when every PR is ineligible, and the poll keeps refetching at 2500ms while anything is running.
• Unused icon imports were cleaned up; pr.Title is now surfaced in the row with a PR #n fallback.

Verified locally: tsc --noEmit clean and vitest run SessionInspector.test.tsx → 11/11 pass.

Minor notes (non-blocking)

• sessionReviewVerdict returns Not run when there are eligible PRs that are a mix of up_to_date and needs_review (since every(up_to_date) is false). That's defensible, but a partially-reviewed session reading "Not run" may surprise; consider a "Partially reviewed"/in-progress state if it matters.
• reviewVerdict collapses both needs_review and ineligible to Not run (ineligible rows only differ by opacity-70). Fine as a simplification, but an ineligible PR (draft/closed) reading "Not run" is slightly ambiguous.
• Styling now leans on a large set of new BEM classes in styles.css (reviewer-row*, reviewer-kicker, etc.); worth a quick visual pass against the agent-orchestrator reference per the design-system guidance.

[neversettle17-101]

When eligible PRs are a mix of up_to_date and needs_review, this falls through to Not run (the every(up_to_date) check fails). Defensible, but a partially-reviewed session showing "Not run" can read as misleading — consider an in-progress/partial label.

AO re-review — feat: show multi-PR review status (frontend)

Verdict: Approve.

fix: remove review session label is a small, clean follow-up: the review card header now shows a static "Pull requests" label instead of the worker session id + "review session" subtitle, with the .reviewer-card__session style renamed to .reviewer-card__label and the test updated to assert the old strings are gone. Behavior is otherwise unchanged. tsc --noEmit clean and vitest run SessionInspector.test.tsx → 11/11 pass.

Minor note (non-blocking)

• Removing the identity block leaves .reviewer-card__name and .reviewer-card__identity in styles.css (around lines 1031/1056) with no remaining component references — dead CSS worth dropping in a cleanup.
