fix: clean sfload with _allocCStr helper + printErr debug + verbose FluidSynth

Browse Source 
- Thay MEMFS path từ /soundfonts/ → root / (tránh lỗi thư mục)
- Helper _allocCStr + _tryLoadSFL: unique filename, manual C string alloc, cleanup
- Thêm printErr callback để capture FluidSynth C stderr log
- Bật synth.verbose=1, synth.ladspa.active=0
- Loại bỏ _fluid_synth_get_sfont_count (không export)
- Log buffer magic bytes (RIFF/sfbk) để verify file valid
