Performance: Consolidated multiple preg_replace calls into a single, efficient regex pass. Support: Added handling for YouTube Shorts, Music, and Embed links. Features: Enhanced link detection to preserve video timestamps (?t=...). Robustness: Improved URL sanitization to prevent broken links (double slashes) and added rel="noopener" for security. UI: Cleaned up the footer note by displaying a clickable hostname instead of the full URL.
