Initial release: ComfyUI-MisoTTS (modernized CSM 8B)

Modernized MisoTTS integration for ComfyUI with no torchtune/moshi:
- vendored plain-torch Llama backbone (csm_llama), parity-verified Δ=0 vs torchtune
- transformers.MimiModel codec (bit-identical codes to moshi), drops moshi/bnb/sphn
- low-memory loader: streams 32GB fp32 checkpoint to GPU in bf16 (~18GB VRAM)
- nodes: Model Loader, Generate (audiobook chunking + voice anchoring), EPUB Loader
- pin-free requirements; runs on modern torch / Blackwell GPUs
