Improve model card: Add pipeline tag, library, project page, and sample usage

This PR enhances the model card by:

- Adding `pipeline_tag: text-generation` for better discoverability on the Hugging Face Hub (e.g., at https://huggingface.co/models?pipeline_tag=text-generation).
- Adding `library_name: transformers` to correctly identify its compatibility with the Transformers library and enable the automated usage widget.
- Including a link to the project page: [Hugging Face Collection](https://huggingface.co/collections/Gen-Verse/trado-series-68beb6cd6a26c27cde9fe3af).
- Incorporating a sample usage code snippet from the GitHub README to guide users on how to interact with the model.

+## Usage
+
+You can download and try our model:
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+from generate import block_diffusion_generate
+
+model_name = "Gen-Verse/TraDo-8B-Instruct"
+
+model = AutoModelForCausalLM.from_pretrained(
+    model_name, trust_remote_code=True, torch_dtype="float16", device_map="cuda"
+)
+tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
+
+prompt = "What's the solution of x^2 - 2x + 1 = 0\
+Please reason step by step, and put your final answer within \\\\boxed{}.\
+"
+messages = [{"role": "user", "content": prompt}]
+text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+
+tokens = tokenizer.batch_encode_plus([text], return_tensors='pt', padding=True, truncation=True, max_length=200)
+tokens = {k: v.to(model.device) for k, v in tokens.items()}
+
+output_ids = block_diffusion_generate(
+    model,
+    prompt=tokens,
+    mask_id=151669,
+    gen_length=200,
+    block_length=4, denoising_steps=4,
+    temperature=1.0, top_k=0, top_p=1.0,
+    remasking_strategy="low_confidence_dynamic",
+    confidence_threshold=0.9
+)
+
+output_text = tokenizer.decode(output_ids[0], skip_special_tokens=False)
+cleaned_text = output_text.replace('<|MASK|>', '').replace('<|endoftext|>', '')
+print(cleaned_text)
