feat(05-01): wire waveform resolution into NewLayer at construction time
- NewLayer resolves WaveformPresetHarmonics when cfg.WaveformType != WaveformCustom
- Preset harmonics stored in Layer.Config so AdvanceSample uses them unchanged
- WaveformCustom path preserves existing hand-tuned harmonics (backward compatible)
- TestNewLayerResolvesWaveformPreset: verifies preset fills harmonics on construction
- TestNewLayerPreservesCustomHarmonics: verifies hand-tuned harmonics are untouched
- TestSineRegressionVsCustomHarmonics: verifies WaveformSine == {Ratio:1,Amp:1.0}
- All 41 synth tests pass, encode tests unaffected

test(05-01): add failing tests for WaveformType and WaveformPresetHarmonics
- TestWaveformPresetHarmonics_Sine: expects exactly {Ratio:1, Amplitude:1.0}
- TestWaveformPresetHarmonics_Square: expects odd harmonics with 1/k amplitude below Nyquist
- TestWaveformPresetHarmonics_Sawtooth: expects all harmonics with 1/k amplitude below Nyquist
- TestWaveformPresetHarmonics_Triangle: expects odd harmonics with alternating 1/k^2 amplitude
- TestWaveformPresetHarmonics_Custom: expects nil return
- TestBandlimitedHarmonicsNoAliasing: checks all ClassFreqConfigs entries at all waveform types
- TestWaveformPresetHarmonics_SquareOddOnly: odd ratios only
- TestWaveformPresetHarmonics_TriangleOddOnly: odd ratios only
- TestWaveformPresetHarmonics_SawtoothConsecutive: consecutive ratios starting at 1
