fix: cast lm_head and all params to bfloat16 to resolve dtype mismatch
KinchiQwen3 with 4-bit quantization + bnb_4bit_compute_dtype=bfloat16 left the lm_head, embed_tokens, and LayerNorms in float32, causing: RuntimeError: expected scalar type Float but found BFloat16 during the lm_head matmul on bf16 hidden states. - Import torch - Set explicit torch_dtype=torch.bfloat16 in every loading path (Unsloth, transformers fallback, transformers without 4-bit) - Add cast_model_to_bfloat16() helper that walks every parameter and buffer, force-casting any float32/float16 tensor to bfloat16 while safely skipping uint8/int8 quantized weights - Apply the cast both BEFORE LoRA (so adapters inherit bf16) and AFTER LoRA (since LoRA spawns adapters in fp32 by default) - Add explicit BitsAndBytesConfig in the no-Unsloth fallback path - Log the lm_head dtype at startup for verifiable confirmation Made-with: Cursor029d5f5
