## Summary

- load every accessible repository page in the background so picker search covers the complete installation set - keep a user-scoped snapshot in `sessionStorage` and revalidate stale pages through stateless ETag pass-through while API responses remain `no-store` - invalidate tab data on logout, account changes, and GitHub App setup, with retry and partial cold-load handling

## Testing

- `bun test` (839 passed, 2 skipped) - `bun run types` - `bun run ci` - `bun run e2e -- hosted.e2e.ts` (12 passed)
