Describe the bug
Unsloth cannot convert fine-tuned model based on unsloth/phi-4 to GGUF because embedded llama.cpp does not support the architecture LlamaModel which was embedded in phi-4 by unsloth/phi-4 as a bug fix.

1. Environment Setup:
   • OS: [e.g., Ubuntu 2.04]
   • Python Version: [e.g., 3.10]
   • Frameworks/Libraries: unsloth
   • colab / script - was this run in colab or as a script: trying both and same result llama.cpp error (no support for LLamaModel.

2/3. Model Details:

• Model ID: unsloth/phi-4
• Model Configuration: [e.g., lora params, quantization, etc.]

4. Training Configuration:

   • Trainer Args: Not Applicable

5. Reproduction Steps:

   • Minimal script to reproduce error:
     model.save_pretrained_gguf(
     "phi-4-finetune",
     quantization_type = "Q8_0",
     )

6. Expected Behavior:

   • Convert to GGUF

7. Actual Behavior:

   • llama.cpp used for conversion in the script fails to convert the phi-4 fine-tune as the morphed architecture is not supported by llama.cpp
