This is a AFK system with the following features:

/afk [reason]
Command

• Toggle AFK status on/off for the player
• Optionally accepts a custom AFK reason (e.g., /afk brb dinner)
• Broadcasts to the server when a player goes AFK or returns
• Updates the player's tab list name and tab suffix with a [AFK] tag

Auto-Unmark AFK
The script automatically removes AFK status when a player:

1. Moves (on player move)
2. Chats (on chat)

Both events broadcast a return message and reset the tab list name/suffix.

Cleanup on Quit

• Clears the AFK variable and resets tab suffixes when a player disconnects
