Improve model card: add metadata, links, and usage info

Hi, I'm Niels from the community science team at Hugging Face.

This PR improves the model card for the DECS NRP Detector by:
- Adding `library_name: transformers` and `pipeline_tag: text-generation` to the metadata.
- Adding links to the associated paper, GitHub repository, and project page.
- Including a sample usage section based on the official GitHub repository instructions.
- Updating the citation block to reflect the latest information.

These changes help users discover, understand, and run the model more easily.

 # DECS NRP Detector 
 
-This repository contains the NRP detector model used in the DECS algorithm. It is designed to determine
-whether a given reasoning chunk contains the ground truth signal.
+This repository contains the NRP (Next Reasoning Point) detector model used in the DECS algorithm, as presented in the paper [Overthinking Reduction with Decoupled Rewards and Curriculum Data Scheduling](https://huggingface.co/papers/2509.25827). 
+
+The NRP detector is designed to determine whether a given reasoning chunk contains the ground truth signal, enabling surgically precise token-level rewards to reduce "overthinking" in reasoning models.

+## Usage
+
+According to the official repository, you can deploy the NRP detector using `vLLM`:
+
+```bash
+vllm serve --model pixas/DECS_NRP_DETECTOR --port 10041 
+```
