Fix CLI command structure to avoid double nesting

- Register individual command functions directly instead of Typer apps
- This fixes the issue where commands required double nesting (e.g. 'codegen init init')
- Now commands work as expected: 'codegen init', 'codegen login', etc.
- Config command remains as a Typer app since it has subcommands
