Noir::JavaCalleeExtractor::MethodIndex

Every method_declaration directly in a class or interface body, by {class name, method name}, in tree order. Spring resolves callees for every route of a file against one root, and walking the whole tree per route made a controller with N handlers cost O(N²) — build it once and pass it as method_index:, like decl_index:. only_class indexes just that class, for a caller resolving a single method.
