Add pipeline tag and sample usage

This PR improves the model card by adding the `text-generation` pipeline tag to the metadata and including a "Sample Usage" section with a code snippet from the official GitHub repository to demonstrate how to load the multi-agent system.

 ⚠️ **Note:** This checkpoint contains **Outer RecursiveLink modules** in [**RecursiveMAS**](https://arxiv.org/abs/2604.25917), rather than a standalone model intended for plain-text generation.

+## Sample Usage
+
+You can load the full multi-agent system (MAS) including these modules using the following code snippet from the [official repository](https://github.com/RecursiveMAS/RecursiveMAS):
+
+```python
+from system_loader import load_mas_system
+
+mas = load_mas_system(
+    style="sequential_scaled",
+    device="cuda",
+    trust_remote_code=True,
+)
+
+planner = mas.agents["planner"].model
+critic = mas.agents["critic"].model
+solver = mas.agents["solver"].model
+```
+
+For detailed usage instructions, please refer to the GitHub repository.
