feat: add post-generation audio enhancement nodes
Three new nodes for post-generation quality improvement:
- SelvaHarmonicExciter: multi-band exciter (HPF → tanh saturation → mix)
restores harmonic richness lost in BigVGAN HF reconstruction
- SelvaFlashSR: audio super-resolution via FlashSR basic model
(haoheliu/versatile_audio_super_resolution, requires pip install audiosr)
predicts missing HF content above vocoder reconstruction ceiling
- SelvaOutputNormalizer: BS.1770-4 LUFS normalization + true peak limiting
for consistent loudness on generated outputs (pyloudnorm)
