Desktop app: Recents list shows stale 'closed' status for a reopened GitHub PR, survives app restart

Environment

• Claude Code desktop app (macOS), version 2.1.168
• macOS 26.5.2 (Darwin 25.5.0)

Description

The Recents/sessions list shows a red "closed" status icon for the GitHub PR linked to a session, but the PR is actually open. The PR was closed and then reopened on the same day (via the GitHub UI); since then GitHub reports state: OPEN / closedAt: null (verified with gh pr view --json state,closedAt), yet the app keeps showing the closed badge.

Steps to reproduce

1. Work on a session linked to a GitHub PR.
2. Close the PR on GitHub, then reopen it.
3. Look at the session's PR status icon in the Recents list.

Expected

The status icon re-syncs to "open" after the PR is reopened.

Actual

The red "closed" icon persists. Fully quitting and restarting the desktop app does not refresh it — the stale status appears to be cached and never invalidated after the close→reopen transition (days later it is still shown as closed).

Notes

• The PR has had new commits pushed and its description edited (via gh from within sessions) since reopening, so the cache isn't refreshed by PR activity either.
