🔧 YouTube Mix Handling – Fully Reworked ✅ Improved Mix Detection

isYouTubeMix() no longer falsely detects a Mix when a normal video URL is used:

/watch?v=...

Even if YouTube automatically appends Mix-related parameters like:

list=RD...

➡️ This prevents single videos from being incorrectly treated as massive auto-generated playlists.

🆕 New Helper Function: sanitizeYouTubeSingleVideoUrl()

If a URL contains:

/watch?v= + list=RD...

YouTube "Radio" / Mix parameters

The bot automatically sanitizes it to:

https://www.youtube.com/watch?v=<videoId>

This ensures the bot loads only the intended single video instead of a hidden or auto-generated Mix playlist.

🎵 Updated !play Logic

The !play command now:

Processes the raw input (trackInputRaw)

Applies the sanitized version (trackInput)

✅ Result

Correct video detection

No accidental loading of large Mix playlists

More predictable and stable queue behavior
