Add model card and metadata

This PR adds a comprehensive model card for EvolveR, linking it to the paper [EvolveR: Self-Evolving LLM Agents through an Experience-Driven Lifecycle](https://huggingface.co/papers/2510.16079) and its official GitHub repository. It also adds relevant metadata tags for `library_name` and `pipeline_tag` to ensure the model is correctly categorized and discoverable on the Hub.

+# EvolveR
+
+EvolveR is a framework designed to enable LLM agents to self-improve through a complete, closed-loop experience lifecycle. This repository contains the model weights introduced in the paper [EvolveR: Self-Evolving LLM Agents through an Experience-Driven Lifecycle](https://huggingface.co/papers/2510.16079).

+
+## Description
+Current Large Language Model (LLM) agents show strong performance in tool use but often lack the capability to systematically learn from their own experiences. EvolveR addresses this by introducing a lifecycle comprising:
+1. **Offline Self-Distillation**: Synthesizing interaction trajectories into a structured repository of abstract, reusable strategic principles.
+2. **Online Interaction**: Task interaction guided by retrieved distilled principles to guide decision-making and accumulate behavioral trajectories.
+
+This loop employs a policy reinforcement mechanism to iteratively update the agent based on its performance.
