pub fn resolve_audio_engine_binary() -> Result<PathBuf, String>Expand description
Resolve path to the audio-engine executable.
Prefer audio-engine-artifacts/debug|release (or legacy target/debug|release) found by walking up from std::env::current_exe.
That covers pnpm dev when the app runs inside a macOS bundle (…/target/debug/bundle/…/Contents/MacOS/audio-haxor)
where the sibling audio-engine can be stale, while the real AudioEngine from beforeDevCommand lives
at the workspace audio-engine-artifacts/<profile>/audio-engine. Also works when CARGO_TARGET_DIR is non-default
(compile-time CARGO_MANIFEST_DIR alone is insufficient).
Override for debugging: set AUDIO_HAXOR_AUDIO_ENGINE to an absolute path to the AudioEngine binary.
Release installs use the sibling next to the main executable when no workspace target/ is found.
Tauri bundle.externalBin places audio-engine-<host-triple>
next to the main executable (see scripts/prepare-audio-engine-audioengine.mjs). We spawn via
std::process::Command, not Tauri’s sidecar API, so we must resolve that suffixed name when
plain audio-engine is absent (typical in a shipped .app under /Applications).
