Fix CLI command structure to avoid double nesting

- Remove Typer app wrappers from individual command files
- Convert commands to standalone functions with Typer decorators
- Update main CLI to import and register individual functions
- Fixes the double nesting issue (e.g., codegen init init)
- All commands now work correctly: init, login, logout, profile, style-debug, update
- Config command remains as Typer app since it has subcommands
