Improve command handling logic by Gopher Nerd (#28)

- [+] refactor(commands.go): improve command handling logic
 - Trim the input and check if it starts with the command prefix.
 - Split the input into command and potential arguments.
 - Retrieve the command and check if it exists in the commandHandlers map.
 - Call the handler function for the command if there are no extra arguments.
 - Return false if the input is not a command.
