Improve model card

Hi! I'm Niels, part of the community science team at Hugging Face.

This PR improves the model card for **AgentHijack-Agent**. The updates include:
- Linking the model to its research paper on the Hugging Face papers page.
- Adding a direct link to the GitHub repository for easier access to the code.
- Listing the full author team.
- Formatting the metadata and content for better discoverability and readability.

These changes help researchers and users find, cite, and implement your work more effectively!

+**AgentHijack-Agent** is the action-generation model released with the paper 
+[*AgentHijack: Benchmarking Computer Use Agent Robustness to Common Environment Corruptions*](https://huggingface.co/papers/2605.25707) (ICML 2026).
 
 It is fine-tuned from [`UI-TARS-1.5-7B`](https://huggingface.co/ByteDance-Seed/UI-TARS-1.5-7B) (Qwen2.5-VL architecture) using **Data-Augmented Group Relative Policy Optimization (DA-GRPO)** on the AgentHijack benchmark, with the goal of producing a computer-use agent that remains reliable under *common environment corruptions* (pop-ups, resolution changes, UI marks, subtitles, multi-apps, accidental touches, app minimization, network errors, and verification prompts).
 
 The same checkpoint serves a dual role in the AgentHijack-Agent framework:
-
 1. **Action generator** — produces the next GUI action from screenshots + history.
 2. **Onlooker** — summarizes behavioral changes between consecutive screenshots and performs an initial environment check before execution.
