Topbar status pill shows orange "working" for open PR and draft sessions, contradicting the board's "In review" description

[aprv10]

Summary

A worker session whose status is pr_open or draft is shown as a breathing orange "Working" pill in the session topbar — implying the agent is actively working — while the board files the exact same session under "In review" and the sidebar shows a neutral dot. The three surfaces disagree, and the topbar's reading is the misleading one: a session that has opened a PR and gone idle awaiting review is animated as if it's busy coding.

Expected behavior

For a session with an open or draft PR (agent idle, awaiting review), the topbar status pill should reflect a review/pending state consistent with the board and sidebar — not a breathing "Working".

Actual behavior

• Board: session sits in the "In review" column with a "PR open" / "Draft PR" badge.
• Sidebar: neutral/passive dot.
• Topbar: breathing orange "Working" pill.

The breathing animation specifically signals active agent work, so the topbar tells a story that contradicts the other two views.

Root cause

Two status-mapping functions handle pr_open/draft differently, and the topbar uses the one that has no case for them:

• attentionZone maps pr_open and draft → pending → board "In review":
  frontend/src/renderer/types/workspace.ts:277-280
• workerDisplayStatus has no case for pr_open or draft, so they fall through to default: return "working":
  frontend/src/renderer/types/workspace.ts:158-159
• The topbar SessionStatusPill feeds workerDisplayStatus into STATUS_PILL, where working is { label: "Working", tone: var(--orange), breathe: true }:
  frontend/src/renderer/components/ShellTopbar.tsx (STATUS_PILL, SessionStatusPill)

So pr_open/draft collapse into the "working" bucket — the one bucket that is orange and animates.

Steps to reproduce

1. Spawn a worker and have its agent open a normal PR from the session branch (not failing CI, no review requested/approved → derives to pr_open; a draft PR gives draft).
2. On the board, confirm the session appears in the "In review" column with a "PR open" badge.
3. Open that session.
4. Observe the topbar status pill: it shows a breathing orange "Working", contradicting the board.
