runRemove function

void runRemove(List<String> args)

river_cli remove <feature|page|screen>:<name> — deletes a scaffolded feature directory and unregisters its go_router route. For feature: it also removes the generated model and repository unless --keep-data is passed.

Destructive: prompts for confirmation unless --yes. --dry-run previews.
