refactor(engine): pure cdylib + undo-stack test race fix (M14 R4)

- oakengine is now cdylib-only (no rlib/staticlib consumers anywhere;
  cargo tree verified) — the plugin/external C ABI layer; README and
  docs updated
- cd.yml drops the dylib embedding/re-sign steps (the app no longer
  links it)
- test race root-caused and fixed for good: the global undo stack lock
  is now a re-entrant mutex (parking_lot) shared by every test that
  drives the stack, including the previously unlocked node/render
  families; the render-manager serial-ordering bug (an earlier repro
  test initialized the global manager before the not-initialized test)
  is fixed with a shared SERIAL guard and a manager shutdown
- 5 consecutive parallel runs clean; serial 209/209
