Introduced a new command: command_name

Implemented a new command "command_name" in the CLi with its associated functionalities in the relevant modules. The new command allows the user to set the name field in the manifest file. Main.rs was updated to handle this new command and exhaustive error handling was added to the main function. Also, improved the manifest module for better error handling and added functionalities for getting and setting manifest's name.
