/**
 * A fake reply object for the Bun adapter that collects response information.
 *
 * Since Bun uses the standard Web API Response object instead of a mutable reply,
 * this class provides a way to capture status and body information from guards
 * and other middleware that expect a reply object with `.status().send()` interface.
 *
 * After guards run, the collected information can be used to construct a Response object.
 *
 * @example
 * ```ts
 * const fakeReply = new BunFakeReply()
 * const context = new BunExecutionContext(module, controller, handler, request, fakeReply)
 *
 * await guardRunner.runGuards(guards, context, container)
 *
 * if (fakeReply.hasResponse()) {
 *   return fakeReply.toResponse()
 * }
 * // Continue with normal request handling...
 * ```
