Add paper link, GitHub link, and task category

Hi there! I'm Niels from the Hugging Face community science team. I've noticed this dataset repository is missing some key documentation. This PR adds the relevant task category to the metadata and includes links to the research paper and the official code repository to make the dataset more discoverable and useful for the community. I have also added a brief description of the dataset structure and evaluation modes as described in the paper.

+# PEARL-Bench: Personalized Streaming Video Understanding
+
+[**Paper**](https://huggingface.co/papers/2603.20422) | [**GitHub**](https://github.com/Yuanhong-Zheng/PEARL)
+
+PEARL-Bench is the first comprehensive benchmark designed specifically for **Personalized Streaming Video Understanding (PSVU)**. It evaluates a model's ability to recognize user-defined concepts, localize them at precise timestamps, and answer personalized queries over continuous video streams.
+
+The benchmark comprises 132 unique videos and 2,173 fine-grained annotations with precise timestamps. It supports two evaluation modes:
+- **Frame-level**: Focuses on a specific person or object in discrete frames.
+- **Video-level**: Focuses on personalized actions unfolding across continuous frames.
+
+## Dataset Structure
+
+The dataset is organized as follows:
+
+```text
+data/
+  frame-level/
+    annotations/   # Fine-grained annotations with timestamps
+    output_clips/  # Generated scene clips
+    videos/        # Source video files (.mp4)
+```
+
+## Usage
+
+For detailed instructions on downloading, merging, and extracting the data, as well as running the evaluation pipeline, please refer to the [official GitHub repository](https://github.com/Yuanhong-Zheng/PEARL).
