[General] Cleanup "stale" closed PR red icon?

**Mood:** 😊
**Category:** General

Cleanup "stale" closed PR red icon? In one session, I ahd completed and merged a PR (well copilot actually did which I found inappropriate and wound-up deleting the PR). After this, I continued the session to further refine the work. But the icon for the session in the left view remained as the Red deleted icon for the full duration because the PR was linked as "closed" from then-on.

Start by reproducing the session state on /chat using the reported app version and a merged or deleted pull request. Trace how the left-view session icon reflects the linked pull request state; done means the icon no longer remains a red deleted indicator after the session continues or the pull request state changes.
