Module script (type=module) có document.currentScript === null,
nên libfluidsynth không thể tự locate .wasm file. Fix: pass
locateFile() trả về URL .wasm tương ứng với URL .js đã load.
fluidsynthLoader.js: expose __FluidSynthLocateWasm() trả về
FLUIDSYNTH_JS_URL.replace('.js', '.wasm'). Dùng polling
setInterval thay vì resolve callback cho đáng tin cậy hơn.
soundfontPlayer.js: pass locateFile factory khi gọi factory.
