The live .codex-plugin/plugin.json in the downstream fork was cleaned up
(websiteURL, privacyPolicyURL, termsOfServiceURL, and defaultPrompt
removed) and icon fields were added (composerIcon, logo pointing at
assets/superpowers-small.svg and assets/app-icon.png). Update the
heredoc to produce the same shape so future sync runs don't wipe the
icon fields or reintroduce the removed URL fields.
