Function pipeline

pipeline(...middlewares: MiddlewareExecutor[]): MiddlewareExecutor
Composes middleware executors in left-to-right order (pipeline style).
Parameters
- ...middlewares: MiddlewareExecutor[]
  Array of middleware executors to compose
Returns MiddlewareExecutor
A function that takes a base fetch and returns the pipelined fetch function
Remarks
The first middleware listed wraps outermost (runs first on request, last on response). Request flow: first middleware → ... → last middleware → fetch. Response flow: fetch → last middleware → ... → first middleware.
Example
```
const qfetch = pipeline(withLogger(), withRetry())(fetch);
// Request: logger → retry → fetch
```
