feat: flag vendored clones and make the repo filter navigable

Two Repos-tab quality-of-life changes:

- External/vendored clones (repos with zero of your own commits — e.g. an
  upstream cloned for reference and never pushed to) are measured on
  refresh, cached in stats_cache (RepoStatsEntry.authored), shown with a
  dim ⧉ marker prefixed to the name, and hidden by the persistent
  hide_external_clones config toggle (key `x`, the `S` menu, or
  `vulp list --external|--no-external`). A fork you do commit to stays
  yours, so only true reference clones are flagged.

- Inside the `/` filter box, ↑↓ now move through the live-filtered
  results and Enter opens the highlighted repo/project directly, instead
  of the filter only "locking" on Enter with no way to scroll or select.

 **Deploy drift** below. `--stale-deploy` filters to repos that are `behind`
 or `diverged` (excludes `in_sync` and `null`/not-applicable).
 
+`--no-external` hides vendored/reference clones (repos you have **zero of your
+own commits** in — e.g. an upstream `pterodactyl` you cloned but never pushed
+to); `--external` shows only those. Classification is measured on `vulp refresh`
+(a git-side `--author` scan of your identities, cached in `stats_cache.toml`);
+before the first refresh nothing is classified and both flags match nothing. A
+fork you *do* commit to (even a handful of commits) counts as yours and is not
+external. In the TUI this is the `x` key / the `⧉` marker, and the persistent
+`hide_external_clones` config toggle.
