Add Gradio interface option (app_gradio.py) - Provides optional web UI for users who want interactive interface - Requires separate gradio installation - Complements the simple app.py script

REAL FIX: Disable MPS for chatterbox-tts compatibility - Forces CPU mode on Apple Silicon due to chatterbox-tts MPS tensor issues - Adds clear explanation in UI and README - Prevents 'Placeholder storage has not been allocated on MPS device' errors - Tested and verified working on Apple Silicon

Fix MPS tensor allocation bug - 'Placeholder storage has not been allocated on MPS device' - Fix silence tensor creation for MPS device compatibility - Add safer model component movement to MPS with error handling - Add CPU fallback if MPS component movement fails

Update README with app.py enhancements summary

Add M4 silicon support to performance benchmarks and mentions

Convert to static repository: Disable cloud building, focus on local Apple Silicon use

Fix description length: 51 chars (under 60 limit)

Merge with HF repository, keeping Apple Silicon optimized README

🎙️ Initial upload: Chatterbox-TTS with Apple Silicon MPS optimization - Native MPS GPU support for 2-3x faster inference - Smart text chunking - CUDA→MPS device mapping - Enhanced UI - Complete documentation
