Introduces a new documentation site for CS2-SimpleAdmin using Docusaurus, including developer API references, tutorials, user guides, and module documentation. Removes the CleanModule example and updates FunCommands and ExampleModule. Also updates main plugin and API files to support new documentation and module structure.
Commented out fun command implementations (noclip, godmode, freeze, unfreeze, resize) in funcommands.cs and removed their registration from RegisterCommands.cs. These commands are now intended to be provided by the new CS2-SimpleAdmin_FunCommands external module, improving modularity and maintainability.
