/**
 * CloakingPipeline — runs an ordered chain of CloakingPlugin instances
 * against each proxied request (and optionally its response).
 *
 * Usage:
 *   const pipeline = new CloakingPipeline();
 *   pipeline.use(createHeaderScrubber());
 *   pipeline.use(createSessionIdentity());
 *   const ctx = await pipeline.processRequest(ctx);
 *
 * NOTE: The pipeline is currently used for unit testing and is ready for
 * integration into the proxy request flow. Callers should instantiate a
 * CloakingPipeline from ProxyConfigFile.cloaking, register plugins based
 * on the config, and call processRequest/processResponse around the
 * upstream fetch in claudeProxyRoutes.ts / oauthFetch.ts.
