📄 JaTubePlayer: Related Video Recommendation System

This module enhances JaTubePlayer with a related video recommendation system based on recently played tags and channels. It utilizes yt_dlp and threading to fetch data efficiently.

---

✅ Features Overview

• Tag & Channel Memory System

  • Stores up to 15 recent search tags and channel URLs.
  • Maintains these in recent_tag.json and recent_channel_url.json.

• Recommendation Engine

  • Fetches related videos from:
    • Past search tags (via YouTube search)
    • Channel upload lists (via their channel ID)

• Parallelized Fetching

  • Uses ThreadPoolExecutor for concurrent data fetching.
  • Separate threads for tag-based search and channel video lists.
