Autoclicker

Refactored the file structure to support Minecraft versions 1.21.1–1.21.11.

Added auto-mute functionality with three priority levels:

1. Highest Priority – Manual Toggle
   Pressing F7 instantly sets the game's master volume to zero or restores it (global mute toggle).

2. Medium Priority – Linked Muting
   Automatically mutes when auto-clicking or auto-placing is active (configurable via settings).

3. Lowest Priority – Automatic Focus-Based Muting
   Mutes automatically when the game window loses focus or is minimized, and restores volume when the window regains focus.
