Add library name, pipeline tag and project page link

This PR adds the `library_name` for easy inference, ensures the model can be found using the `text-generation` pipeline tag, and adds the project page for this model.

-This is the default router from the paper [R2R: Efficiently Navigating Divergent Reasoning Paths with Small-Large Model Token Routing](https://arxiv.org/abs/2505.21600). 
+This is the training and validation set used by the paper [R2R: Efficiently Navigating Divergent Reasoning Paths with Small-Large Model Token Routing](https://huggingface.co/papers/2505.21600). This dataset contains token-level routing labels generated to train a lightweight router that selectively uses a Large Language Model (LLM) for critical, path-divergent tokens during inference, improving efficiency without sacrificing accuracy.

+Roads to Rome (R2R) is a neural token router that efficiently combines Large Language Models (LLMs) and Small Language Models (SLMs) by selectively routing only critical, reasoning-divergent tokens to the large model.
