find_pruneable_heads_and_indices and prune_linear_layer were removed from
both pytorch_utils and modeling_utils in some transformers builds. Provide
minimal inline implementations as final fallback — prune_heads() is never
called at inference time so correctness is only needed for completeness.

Some transformers builds removed these from pytorch_utils. Fall back to
modeling_utils which exposes them in all known versions.

Pure PyTorch SelVA source for SelvaModelLoader/FeatureExtractor/Sampler nodes.
Imports rewritten from selva.* to selva_core.*. mel_converter.py: replaced
librosa.filters.mel with pure-numpy implementation to avoid librosa→numba→NumPy
version incompatibility in some ComfyUI environments.
