def register!
  # Idempotent by ASKING THE ROUTER, not by remembering. run! and the CLI
  # both call this, and it can run more than once per process. A boolean
  # flag looked equivalent and was not: Router.clear! (every spec, and
  # any re-init) wipes the routes while the flag stays true, so /health
  # silently vanishes for the rest of the run. Querying the router is
  # self-healing -- cleared routes re-register, present ones don't
  # duplicate.

  # Register at the configured path. The legacy "/health" path stays
  # registered for backward-compat.
