/**
 * Get a stable canonical identifier for the repo's `origin` remote, if any.
 *
 * Used to fingerprint two on-disk clones as the same logical repository
 * (issue #XXX — silent graph drift across sibling clones). `path` alone
 * is unreliable: worktrees, "clean clone for indexing" hygiene, and
 * multi-agent workspaces routinely have the same repo at multiple
 * absolute paths. The remote URL is the only on-disk signal that
 * survives those conventions.
 *
 * Normalisation strategy:
 *   - Strip a trailing `.git` so `https://x/y` and `https://x/y.git` collapse.
 *   - Strip a trailing `/` for the same reason.
 *   - `git@github.com:foo/bar` and `https://github.com/foo/bar` are
 *     intentionally NOT collapsed — they are different remotes from
 *     git's perspective and we don't want to assert equivalence.
 *   - Lower-case the host portion so `GitHub.com` and `github.com`
 *     don't desync; preserves case in path because some hosts
 *     (Bitbucket Server) treat repo paths case-sensitively.
 *
 * Returns `undefined` when there is no origin remote, the directory
 * isn't a git repo, or git itself isn't available.
