Add pipeline tag, library name and sample usage

This PR improves the model card for the Deliberation-Toolcaller-Qwen3.5-4B model.

Key changes:
- Added `pipeline_tag: text-generation` to the YAML metadata for better discoverability.
- Added `library_name: transformers` to the YAML metadata as the model configuration indicates compatibility.
- Included a "Usage" section with a code snippet derived from the official GitHub repository to demonstrate how to load the model within the RecursiveMAS framework.
- Maintained existing links to the project page, code, and paper.

+## Usage
+
+This model is intended to be used as part of the RecursiveMAS framework. You can load the deliberation system as follows:
+
+```python
+from system_loader import load_mas_system
+
+mas = load_mas_system(
+    style="deliberation",
+    device="cuda",
+    trust_remote_code=True,
+)
+
+# Access the specific agents
+reflector = mas.agents["reflector"].model
+toolcaller = mas.agents["toolcaller"].model
+```
+
+Alternatively, you can run inference using the provided script from the repository:
+
+```bash
+python run.py --style deliberation --batch_size 16 --temperature 0.6 --top_p 0.95 --dataset math500 --seed 42 --trust_remote_code 1 --device cuda
+```
