// CRASH SAFETY (mirrors test_boost_dm_lib.cpp / test_boost_dm_be.cpp):
//   * Only TEST(...). gtest_main supplies main(); never define main().
//   * Engine stays Idle; no real mpv play/seek/decode/load is triggered.
//   * We NEVER construct a live MpvProxy/MpvGLWidget (libmpv/GL crash).
//     Only PURE/STATIC pieces of mpv_proxy.cpp are exercised:
//     my_node_autofree on synthetic nodes, MpvHandle null-container ops,
//     tr() strings, Backend::setDebugLevel, getDecodeModel/setDecodeModel
//     (static_cast of a null _current is well-defined and guarded).
//   * isMpvExists() is stubbed for both branches of every gst/mpv fork.
//   * Every Stub is reset() before the test ends.
