ProxyManager v2.0

🚀 Asynchronous Core: Built with asyncio and aiohttp for high-concurrency and blazing-fast performance.
📚 Multi-Source Collection: Gathers proxies from popular online providers and custom text file URLs.
✅ Advanced Health Checks: Tests proxies for TCP connectivity, latency (ms), and download speed (Mbps).
📊 Intelligent Scoring: Ranks proxies based on a weighted algorithm considering latency, speed, and uptime.
💾 Persistent Database: Saves all proxy data to an SQLite database, preventing data loss and enabling historical analysis.
⚙️ Highly Configurable: Easily tweak settings like concurrency, timeouts, and scoring weights via a simple config.yaml file.
🖥️ Interactive CLI Menu: A user-friendly, menu-driven interface powered by Typer and Questionary for easy operation.
graceful Graceful Shutdown: Safely interrupts long tasks (like re-checking) with Ctrl+C and saves the results found so far.
📤 Flexible Exporting: Exports working proxies into clean http.txt, socks4.txt, socks5.txt, and a detailed proxies.json file.
