Switch Space to beyoru/Luna-II

UI to English (labels, description, examples, thinking titles)

Fix: yield string với <details> collapse (ChatInterface không nhận list); strip think khỏi history; dtype thay torch_dtype; cache_examples=False

Tách suy luận (</think>) ra ô collapse riêng; đọc special token để split

Rhapsody-4B chat (Gradio + ZeroGPU, streaming, thinking toggle)
