fix: add init guard, log selectablePresetList count

Browse Source 
- Add missing if (_initialized && _synthInstance) return to init()
- soundBank is main-thread proxy, worklet has actual presets
- Check selectablePresetList.length from soundBankManager (worklet state)
- Log when presets are empty (SpessaSynth parser issue)
