 * Walk parents from `cwd` looking for the nearest enclosing repository
 * root, identified by either a `.git/` directory or a `fjall-config.json`
 * file. Returns the absolute path of the first directory matching either
 * marker, or falls back to `cwd` when no ancestor matches.
 *
 * Used by the CLI scaffold pre-flight so `scanLocalRepository` always
 * walks from the repo root: a `fjall create app` run from
 * `services/api/` still discovers existing markers under
 * `services/worker/fjall/`, not only the descendants of `cwd`.
