• ✅ Tracks and reports the total scan duration

Features

• Recursive Scanning: Scans a website up to a specified depth.
• Concurrent Image Checks: Uses concurrent requests to check images for broken links.
• HTML Report Generation: Generates a detailed HTML report of broken images.
• Configurable via Environment Variables: Allows configuration of log file path, scan timeout, and scan depth.
