fix(mobile): thread rows show Working while background work runs

[Sandesh-Solabannavar]

When a thread's turn settles but its subagents or workflows keep running, web shows the row as Working (the server reports this through backgroundLiveness). The mobile thread list only checked session.status, so the same thread looked idle on mobile and showed the time since the last message.

Fix

• resolveThreadListV2Status now reads backgroundLiveness after the session checks, using the same order as web's resolveSidebarThreadStatus. "working" shows as Working and "monitoring" shows as a new Monitoring status.
• Added a sky-blue Monitoring label to the mobile row, matching web.
• Added a test for both background states.

Not changed: iOS widgets and Live Activity have their own working check and still ignore backgroundLiveness.

Before

Desktop shows the thread as Working 9m. On mobile the same thread shows only "20m", with no status.

(Screenshots to be attached.)

Verification

• vp test run src/features/threads/threadListV2.test.ts (87 passed)
• tsc --noEmit for apps/mobile

Not tested on a device.

Approvability

Verdict: Approved at 347df4f

Macroscope's review found this PR approvable — This is a small, self-contained mobile UI fix that reflects existing background-work state in thread rows and adds matching coverage. Its runtime impact is limited to status presentation, with no product-default, schema, deployment, or static-analysis changes.

📝 Walkthrough

Walkthrough

The thread list status resolver now accounts for background liveness after its existing status checks. It returns working or monitoring when those values apply. The thread list also displays a “Monitoring” label, and tests cover both statuses.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Include Monitoring in the card row’s accessibility label.

When a card changes to "monitoring", the visible text says “Monitoring,” but RowPressable supplies an explicit accessibility label containing only the thread title or queued-message text. Add the resolved status to the card row’s accessibility label so a screen-reader user can identify the new state. Based on learnings, “interactive and dynamic elements should have appropriate ARIA labels, roles, states, and live regions so screen readers announce them correctly.”

Closing: upstream main already covers this. The new orchestrator replaced backgroundLiveness with runtime, and #16693 shows threads with live background work as Waiting on mobile, matching web. This branch was cut from an older main.
