Agent Skills: harper-config-yaml

This skill should be used when creating or editing a Harper (HarperDB/Fabric) component's config.yaml — enabling a built-in extension (graphqlSchema, jsResource, rest, static, roles, loadEnv, dataLoader, fastifyRoutes), wiring an external component, or troubleshooting why an extension is not loading. Critical: it documents the no-merge footgun where a custom config.yaml replaces Harper's default config entirely. Pairs with harper-component-model, harper-resources, and harper-schema-graphql.
