Generating Ui Bundle Metadata

It knows the rules for ui-bundle.json (routing rewrites, headers, outputDir constraints), the uibundle-meta.xml format, and CSP Trusted Site registration. The spec is surprisingly fussy about path safety, empty objects, and what characters you can use in bundle names. Most useful when scaffolding with sf template generate or when your images and API calls are getting blocked because you forgot to register the external domains. It will stop you from writing invalid configs that look fine but fail on deploy.
