+blocking `SemaphoreSlim` in `GodotAdvHost`, UI marshalled with `CallDeferred`. Plays SC0000 page-by-page,
+pauses at wait-for-input, resumes on click/Enter. **Headless self-test** (`--headless -- --selftest`)
+asserts the emitted 186-line offset sequence == `build/vm0-trace.json`; A1 engine tests stay 7/7.
+Toolchain: `godot --headless --path godot --import` → `dotnet build godot/Himegari.csproj` →
