Implement submodule.Provider with the git CLI so submarine reads real repositories: `submarine [dir]`, with `--mock` for the built-in data. - Tree reads .gitmodules recursively; Status derives presence, checkout, worktree, staged pin, pushed state and pin -> ref resolution from local git commands only (no network). - Concurrent Status calls are bounded by runtime.NumCPU(). - scripts/make-fixture.sh builds a superproject covering every state; the integration tests run against it. - theme.Ago shows "never" for a zero time. - Docs updated; decisions D14-D16 added.
