the production values: redirected, noindex and canonicalised addresses
leave the sitemaps with their reason; staging lists the same set
- the plugin requires golem15.sitemap and publishes the filter in Register
- go.mod requires sm-sitemap-plugin, go.work mounts the sibling checkout
- plugin.yaml generated by summer plugin:manifest (name override: SEO)
- TestPluginManifest guards it with kiosk.CheckT
- require SummerCMS v0.6.0, the framework minimum in plugin.yaml
