FixturesInterceptor class

Dio interceptor that serves fixture responses through a FixturePipeline.

Every request is normalized into an HttpFixtureRequest and served by the pipeline — sources, selection strategy, picker, memory and delay all live there. This interceptor only renders the outcome in Dio's terms: a FixtureServed becomes a Response whose status comes from the document's description, and a FixtureMiss rejects with a DioException whose error is the miss itself, so callers can branch on FixtureNotFound, FixtureEmpty, or FixtureCancelled.

final pipeline = FixturePipeline(
  source: HttpFileFixtureSource(),
  selector: DataSelectorType.pick,
  view: FixturesDialogView.of(context),
);
dio.interceptors.add(FixturesInterceptor(pipeline: pipeline));

Build the pipeline once, next to the Dio instance: remembered choices live in it. Served responses are stamped with documentHeader (and filePathHeader when the payload is an external file); read them through ResponseOrigin.of.
