Use pruned 536M model with vocab mapping support

- Model shrunk from 722M to 536M via vocabulary pruning (255K→80K tokens)
- Add custom autoregressive generation (no HF .generate() dependency)
- Add vocab_mapping.json support for tokenizer→model ID translation
- Update model size references throughout
