CLI commands

Command	What it does
init	Write textui.config.json and create the component directories
add <names...>	Copy components and their dependencies
create <template>	Scaffold a template, pulling in the components it composes
list	Registry components, templates and themes; --catalog for the built-ins
theme [name]	List themes, preview one, or --set the project default
registry add <name> <path>	Register another registry
diff	What has drifted from upstream
doctor	What this terminal can do, and what the project looks like

Useful flags: --dry-run on add shows what would be written and writes nothing; --json on list and doctor gives machine-readable output.
