Noir::TreeSitterGoRouteExtractor::GfMetaRoute

GoFrame's standardized routing: a request struct embeds g.Meta whose struct tag carries the route (path:"/x" method:"get"), and group.Bind(controller) wires every such method up. The tag is the route definition — it's exactly what gf's own OpenAPI generator reads — so we surface it directly. params are the struct's own request fields (json-tag name or field name); the analyzer types them by HTTP method.
