"""Kintsugi core loader — real package first, vendored copy as fallback.

Resolution order:
  1. `KINTSUGI_PATH` env var pointing at a Project-Kintsugi checkout
  2. an installed/importable `kintsugi` package
  3. the vendored verbatim copy in v2/kintsugi_vendor/

Everything downstream imports Kintsugi symbols from THIS module, so the
same Rivet code runs against the real engine on a dev box and against
the vendor copy on a bare deployment target.
