Load discovers OpenAPI specs in opts.SpecsDir, parses each one, applies per-spec user configuration, and classifies every operation. It is designed to be tolerant: a bad spec produces a warning and is dropped from the registry, but never aborts loading other specs. Per-operation classification failu
