Cano's AutoRun

This major update makes the autorun mode more stable and visually appealing, similar to clients like Lunar and Feather. This update will initially be available for version 1.21.x, and later I will release the same update for 1.20.x while keeping the exact same format. Additionally, the code structure has been improved, a bug that caused lag has been fixed, and the issue that occasionally stopped sprinting has also been resolved.
