fix: corrected click context management in TutorCli, resolves #14

[Abdul-Muqadim-Arbisoft]

Removed manual patching of TutorCli object to address an issue where click_repl incorrectly accessed the commands attribute. This patch previously enabled nested shell functionality, which introduced complexity and unexpected behavior.

Following is what I am getting over webui interface

Welcome to the Tutor interactive shell UI!
Type "help" to view all available commands.
Type "local launch" to configure and launch a new platform from scratch.
Type <ctrl-d> to exit.
> help
Usage: tutor [OPTIONS] COMMAND [ARGS]...

Error: No such command 'help'.

Unhandled exception in event loop:

Press ENTER to continue... 

It doesn't recognize help command as well as when I want to enter local start, after writing local and pressing spacebar it throws exception, as seen in above logs
