[Bug]: Snoozed idle thread shows in the Snoozed section but stays in the active sidebar list

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/desktop

Steps to reproduce

1. Pick an idle thread (no run in progress, provider session stopped).
2. Open the thread actions and choose Snooze.
3. Set a custom wake time a few days out.
4. Look at the sidebar.

Expected behavior

The thread leaves the active list. It shows only in the Snoozed section until its wake time.

Actual behavior

The thread shows in the Snoozed section with the correct wake time. It also stays in the active list. It never goes away until I settle or archive it.

The server state looks correct. Two threads I snoozed today, read from projection_threads:

	Thread A	Thread B
snoozed_at	2026-10-06T16:13:07Z	2026-10-06T16:13:18Z
snoozed_until	2026-10-10T17:13:00Z	2026-10-10T17:13:00Z
pinned_at / settled_at / archived_at	null	null
pending approvals / user input / plan	0 / 0 / 0	0 / 0 / 0
session status	stopped	stopped
unsettled_at	null	2026-10-04T12:26:30Z

So snoozed_until is in the future, but the desktop sidebar still renders the thread in the active list.

Impact

Snooze doesn't clear the sidebar, so I can't park threads. I run many threads at once, so the active list stays cluttered.

Version or commit

T3 Code (Alpha) 0.0.45 desktop (Electron 44.4.2), server t3 v0.0.45

Environment

macOS desktop client connected to a remote t3 serve on a Mac mini.

Workaround

None. Settling or archiving the thread hides it, but that is not the same as a timed snooze.
