Virtuals carry a `parallel_fetch` flag in the v2 API, but the UI type omits it and neither the UI nor the TUI displays it, so the setting is invisible to operators.
- add `parallel_fetch` to the TS `Virtual` type
- add a Parallel column with a yellow badge to the UI virtuals table
- use one `selected` lookup for the virtual detail panel
- add a parallel column to the TUI virtuals list, padding the member count (`%3d members`) so columns align

github_rpm remotes regenerate repomd and all three gz files from every metadata row on each request, which is expensive for large repos under repeated dnf traffic.
- add a per-remote `cache_repodata` toggle (column, model, v2 API, docs)
- cache built repodata per replica, rebuilt via singleflight when the `count(*)`+`max(id)` row fingerprint moves
- store a build only if no newer build has landed; evict idle entries hourly
- map cached-path DB errors like the uncached path: 503 + Retry-After on cancel/deadline, generic 500 otherwise
- check `cacheEmpty` via the fingerprint for all github_rpm remotes, not only cached ones

Virtual merges expire after 60s and the next request blocks on every member. One slow member (a large github_rpm remote) makes the re-merge outlast dnf's 30s timeout.
- add `serve_stale` to remotes (model, v2 API, migration 0008, UI, TUI), default false
- serve a flagged member's last good fetch to rpm/deb/alpine merges at once
- refresh it in the background, single-flighted, detached from the request
- block on the member again once its copy is over an hour old, or the flag is off
- prune copies with their merge cache; drop refreshes for evicted entries
