Main script for the leaderboard parser.
This script processes leaderboards specified in data/best_model_for_category_list.json file
by matching their UIDs with hosts in data/final_leaderboards.json.

Environment variables:
    HUGGING_FACE_HUB_TOKEN: Authentication token for Hugging Face Hub (required)
    HUGGING_FACE_STORAGE_REPO: Target dataset name on the Hub (optional, default: leaderboard-explorer/leaderboard_explorer)
    LEADERBOARD_REPROCESS_INTERVAL_HOURS: Interval in hours between leaderboard processing runs (default: 24)
