Chat command enhancer

--[[
Roblox Chat Command Enhancer (LocalScript)
Adds extra chat commands & text modifiers

Commands:
!chat reverse <text>
!chat corrupted <text>
!chat mimic <player>
!chat mimic stop

Text modifiers:
#smile  -> 😃
#sad    -> 😔
/n      -> newline

Other:
>console <message>   -> prints to console
$execute <lua>       -> executes Lua code (local)

NOTE:
- LocalScript only affects YOUR client.
- Uses TextChatService (new chat). Falls back if needed.
- $execute is powerful. Use only for testing.
