/**
 * Resolve the default branch of a local clone from `refs/remotes/<remote>/HEAD`.
 *
 * `git clone` sets this symbolic ref to the remote's default branch (the one
 * GitHub/GitLab marks as default), so a repo cloned with `master` as its
 * primary branch reports `<remote>/master` and one on `main` reports
 * `<remote>/main`. Reading it locally means no network round-trip and no
 * per-repo config to maintain.
 *
 * Best-effort: when the HEAD ref is unset (rare — e.g. an out-of-band clone or
 * a `git remote set-head --delete`) or git otherwise fails, fall back to the
 * caller-supplied default so worktree creation and branch probes keep working.
 * Abort signals still propagate so a cancelled run doesn't waste time on the
 * fallback path.
