Add model card and metadata

This PR adds a comprehensive model card for OCRVerse. It includes:
- Metadata tags for `pipeline_tag`, `library_name`, and `license`.
- Links to the [OCRVerse paper](https://huggingface.co/papers/2601.21639) and [GitHub repository](https://github.com/DocTron-hub/OCRVerse).
- A sample usage code snippet for document parsing using the `transformers` library, as provided in the official repository.

+# OCRVerse: Towards Holistic OCR in End-to-End Vision-Language Models
+
+OCRVerse is a holistic OCR method that enables unified text-centric OCR (extracting text from documents like books and magazines) and vision-centric OCR (identifying visual elements from information-dense sources like charts, web pages, and scientific plots) in an end-to-end manner.

+## Usage Example
+
+To use OCRVerse, please ensure you have the `transformers` library installed:
+
+```shell
+pip install "transformers>=4.57.0"
+```
+
+### Text-Centric Document Parsing
+
+Below is a simple example of how to use OCRVerse for document parsing tasks.
+
+```python
+from transformers import Qwen3VLForConditionalGeneration, AutoProcessor
+import torch
+
+# Load model
+model_path = 'DocTron/OCRVerse'
+model = Qwen3VLForConditionalGeneration.from_pretrained(
+    model_path,
+    dtype="auto", 
+    device_map="cuda",
+    trust_remote_code=True
+)
+processor = AutoProcessor.from_pretrained(model_path, trust_remote_code=True)
+
+# Prepare input with image and text
+image_path = "path/to/your/image.jpg"
+# We recommend using the following prompt for better performance
+prompt = "Extract the main content from the document in the image, keeping the original structure. Convert all formulas to LaTeX and all tables to HTML."
+
+messages = [
+    {
+        "role": "user",
+        "content": [
+            {"type": "image", "image": image_path},
+            {"type": "text", "text": prompt},
+        ]
+    }
+]
+
+# Preparation for inference
+inputs = processor.apply_chat_template(
+    messages, 
+    tokenize=True, 
+    add_generation_prompt=True,
+    return_dict=True,
+    return_tensors="pt"
+)
+inputs = inputs.to(model.device)
+
+# Inference: Generation of the output
+generated_ids = model.generate(**inputs, max_new_tokens=8192, do_sample=False)
+
+generated_ids = [
+    output_ids[len(input_ids):] for input_ids, output_ids in zip(inputs.input_ids, generated_ids)
+]
+output_text = processor.tokenizer.batch_decode(
+    generated_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False
+)
+print(output_text[0])
+```
