Session list PR status chip always renders greyed out despite gh + backend reporting correct state

What happened

In the Claude Code desktop app, each session that has an associated pull
request shows a PR status chip in the session list. This chip is always
rendered greyed out (as if the state were unknown/pending), regardless of
the PR's actual state on GitHub.

I verified that the underlying data is correct and available at every layer
except the rendered chip:

1. gh CLI resolves state correctly:

``
$ gh pr view <N> --repo <org>/<repo> --json number,state,title
{"number":<N>,"state":"OPEN","title":"..."}
``

1. The session backend already knows the state — the session metadata

returns the correct prState:
``
{ "title": "...", "prNumber": <N>, "prState": "OPEN", ... }
``

1. But the UI chip is still grey for that same session.

So both the gh data source and the session backend report OPEN, yet the
chip never reflects it. This looks like a rendering / state-mapping bug in
the desktop app rather than a gh auth or network problem.

Secondary observation

Of the PR-related sessions in the list, only a couple had a prNumber
associated at all; the rest had no PR linkage. For those the grey chip may be
"correct" (no PR linked), but the association seems to be missed for most
sessions that did create/work on a PR.

Impact

• PR state is never visible at a glance in the session list.
• "Auto-archive after PR merge or close" appears to never fire (it relies on

the same state signal), so archiving must be done manually.

Steps to reproduce

1. Have a session with an associated open PR.
2. Confirm gh pr view <n> returns OPEN.
3. Observe the session-list PR chip — it stays grey.

Environment

• Claude for Windows (desktop app): 1.9659.2 (390d6c)
• Claude Code engine: 2.1.90
• gh CLI: 2.88.1 (authenticated, scopes include repo)
• OS: Windows 11 (10.0.26200.8390)

Expected

The PR chip should reflect the resolved PR state (open / merged / closed),
matching what gh and the session backend already report.
