This PR improves the dataset card by:
1. Adding the `text-generation` task category to the YAML metadata.
2. Linking the dataset to the original research paper: [Generating Expressive and Customizable Evals for Timeseries Data Analysis Agents with AgentFuel](https://huggingface.co/papers/2603.12483).
3. Formatting the content with Markdown headers and bullet points for better readability.
