Improve model card: Add metadata and sample usage

This PR enhances the model card by adding crucial metadata and a clear sample usage section:

- `pipeline_tag: robotics`: Categorizes the model for better discoverability under robotics/navigation tasks.
- `library_name: transformers`: Ensures compatibility with the Hugging Face Transformers library is indicated, enabling the automated "Use in Transformers" widget, based on `config.json` evidence.
- `license: cc-by-nc-sa-4.0`: Formally specifies the model's license, consistent with the existing badge and GitHub repository information.
- `tags`: Added `vision-language-model` and `navigation` for further discoverability.
- The official Hugging Face paper link is added under the title for immediate visibility.
- A Python code snippet for sample usage with the `transformers` library is included, adapted to demonstrate how to load and use the model for inference, based on the model's `transformers` compatibility and the typical usage pattern for such models.

These updates aim to provide users with more complete information and an easier getting started experience.

-## Usage
-For inference, evaluation, and the Gradio demo, please refer to the [InternNav repository](https://github.com/InternRobotics/InternNav).
+## Sample Usage
+
+This model is compatible with the Hugging Face `transformers` library. The following code snippet demonstrates how to perform inference:
+
+```python
+import torch
+from PIL import Image
+from transformers import AutoProcessor, AutoModelForCausalLM
+import requests
+from io import BytesIO
+
+# Load model and processor
+hf_model_id = "InternRobotics/InternVLA-N1-DualVLN"
+model = AutoModelForCausalLM.from_pretrained(hf_model_id, torch_dtype=torch.float16, trust_remote_code=True, device_map="cuda")
+processor = AutoProcessor.from_pretrained(hf_model_id, trust_remote_code=True)
+
+# Load a dummy image
+# Replace with your actual image path or a URL to a relevant scene
+image_url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/bird_image.jpg"
+image = Image.open(BytesIO(requests.get(image_url).content)).convert("RGB")
+
+# Define a question related to navigation or visual understanding
+question = "What is the most direct path to the kitchen from here? Describe the first few steps."
+
+messages = [
+    {"role": "user", "content": f"<|image_pad|>{question}"},
+]
+
+# Process inputs
+inputs = processor.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt")
+inputs = inputs.to(model.device)
+pixel_values = processor.preprocess(images=image, return_tensors="pt")["pixel_values"]
+pixel_values = pixel_values.to(model.device, dtype=torch.float16)
+
+# Generate response
+with torch.inference_mode():
+    outputs = model.generate(
+        **inputs,
+        pixel_values=pixel_values,
+        do_sample=True,
+        temperature=0.7,
+        max_new_tokens=1024,
+        eos_token_id=processor.tokenizer.eos_token_id,
+        repetition_penalty=1.05
+    )
+
+response = processor.decode(outputs[0], skip_special_tokens=True)
+print(f"User: {question}
+Assistant: {response}")
+```
