Add voice similarity control + improve reference audio processing

Replace RVC with Seed-VC for zero-shot voice conversion

Implement real RVC v2 inference pipeline with HuBERT + FAISS + generator

Convert pretrained checkpoint to RVC inference format for proper voice conversion

Skip HiFi-GAN training entirely, use pre-trained model + FAISS index

Better error messages + reduce segments to 40 for GPU time limit

Restore full quality params now that GPU is available

Reduce all @spaces.GPU durations to 60s (ZeroGPU max limit)

Skip HiFi-GAN training on CPU, use pre-trained model + FAISS index

Optimize training for CPU: limit slices, reduce batch size and epochs

Fix 'context has already been set' multiprocessing error

Replace Applio preprocess subprocess with custom implementation

Search for sliced audio recursively and show directory tree in errors

Add detailed logging to preprocessing to debug missing audio slices
