Fifth incremental variable — and the first genuinely heavy one. Adds:
- cpp/oboe_bridge.{h,cpp} (copied verbatim from crates/wzp-android/cpp/)
- cpp/oboe_stub.cpp (fallback if Oboe can't be fetched)
- build.rs now clones google/oboe@1.8.1 into OUT_DIR and compiles
oboe_bridge.cpp + every .cpp file under oboe/src/ as a single
static library via cc::Build, using shared libc++. Same logic as
the legacy wzp-android build.rs.
- libc++_shared.so gets copied from the NDK sysroot into the Tauri
gen/android jniLibs directory so the runtime linker can find it.
- rustc-link-lib=log / OpenSLES emitted for Oboe's Android backends.
Deliberately NOT called from Rust yet — no extern "C" FFI declarations,
no oboe_audio.rs module, the `wzp_oboe_*` symbols from the static lib
are simply present but unreferenced.
Goal: isolate whether the Oboe C++ compile + static lib link alone
(with its libc++ dependency and log/OpenSLES bindings) regresses the
working baseline. If the build still launches and renders the home
screen, we know the C++ side is clean and the actual regression is
caused by calling into Oboe at runtime (next step).
