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.
