fix: ScriptProcessorNode fallback + worklet process() logging
...
- ScriptProcessorNode fallback khi AudioWorkletNode fails
- Render trực tiếp trong onaudioprocess callback, không cần setInterval
- Worklet log peak + queue depth mỗi 50 process() calls
- Log audioCtx state + sampleRate khi init

fix: AudioWorklet bridge xử lý sai frame → silence
...
process() gán Float32Array (cả frame 512 samples) vào out[0][i]
thay vì sample riêng lẻ → NaN → silence.
Fix: track fi (frame index) + si (sample index), đọc qL[fi][si].

feat: migrate SpessaSynth → FluidSynth WASM (SF3 native, loop Gen 54 fix)
...
Replace SpessaSynth JS/AudioWorklet with FluidSynth C++ WASM
(@enikey87/fluidsynth-emscripten@0.1.1). CDN for dev, self-host
for prod. Fixes stuck Tremolo/Saxophone notes via compliant
Gen 44 loop mode processing. 100% audio parity with server
pyfluidsynth render (same C++ core).
- soundfontPlayer.js: FluidSynth WASM engine, preserve SonicSF API
- fluidsynthLoader.js: auto-select CDN (dev) vs self-host (prod)
- fluidsynth-bridge.js: PCM bridge AudioWorklet processor
- index.html: remove SpessaSynth importmap + module, add loader
- vendor/: libfluidsynth-2.3.0-sf3.js + .wasm (1.8MB self-host)
