  "state": "OPEN",

  "body": "## Summary\n\nIntroduces a cached repository query so the titlebar picker can switch context without hitting GitHub on every open.\n\n### Why\n- reduces flicker while the picker opens\n- keeps recent repositories visible during short reconnects\n- avoids duplicate requests when the titlebar rerenders\n\n### Cache rules\n- explicit refresh invalidates the cached list\n- fresh network data still wins when available\n- empty responses should not overwrite a warm cache\n\n```text\nopen picker -> read cache -> render immediately -> refresh in background\n```\n\n### Follow-up\n1. Measure cache hit rate in debug builds.\n2. Add eviction telemetry.\n3. [ ] Consider persisting the last successful repository list across launches."
