feat(git): home polish + repo-card dashboard in the feed

Home screen:
- Nav cards: tighter vertical spacing; badges now count only OPEN issues/PRs,
  derived from the live GitStatusIndex (started on the home so the split is
  correct without visiting the Issues screen first).
- Moved the reaction row to after the recent-activity pulse.
- Added the standard 3-dot note menu (MoreOptionsButton) to the top bar.

Feed card (RenderGitRepositoryEvent):
- Replaced the web/clone links with the same stat tiles + language bar +
  last-commit strip used on the home, loaded from a lazily-fetched shallow
  snapshot. (Factory made internal so the card can build the browser VM.)
