that's good, but pull request to the wiki is better.

it look like something wrong with your DNS

minecraft always sync current slot before click, you may have a try

the disconnect function is used to actively disconnect to the server. you should use listener on disconnect packet or use handle_exit

you should close this issue if you understand

This project is a networking library. You may search some method handling right click in minecraft source code(use yarn or mcp) and see what packet will be sent if player...

check your credentials, username or password if it can be used in minecraft first

see how minecraft do it first(yarn or mcp)

That's good. But it is not an issue.
