ApprovabilityVerdict: Approved at Macroscope's review found this PR approvable — This is a small, well-scoped bug fix that prevents completion and unread indicators from firing while existing background work remains active. It reuses established thread state and statuses, adds targeted regression tests, and does not change product defaults or static-analysis configuration. You can add or adjust custom eligibility rules.

- Line 101: Update the thread presentation resolver around the
backgroundLiveness check to handle "monitoring" after the parent turn settles
with a dedicated mobile Monitoring presentation, separate from the existing
"working" presentation and without a pulse; preserve the current behavior for
"working" and null/other states.

Add a mobile Monitoring presentation for live watch loops.
When backgroundLiveness === "monitoring" after the parent turn settles, this resolver skips the "working" branch and returns null. The contract defines monitoring as live background work. The web resolver presents it separately from Working, without a pulse. Add a mobile Monitoring presentation instead of treating every non-null value as Working.

What Changed
Why
A parent turn can have a completion timestamp while delegated subagents are still running. The web status model already understood that state, but remote notification and unread-state consumers could read the timestamp by itself and report a false completion.
This uses the existing
backgroundLivenesssignal. It does not add a delay, notification store, or provider-specific path. Approvals, questions, and failures still take priority and notify immediately.Closes #5518.
