.SYNOPSIS
  Orchestrates the FOCAS driver integration-test loop: bring up the
  focas-mock Docker container, run the managed wire-client integration
  tests, tear down Docker.

.DESCRIPTION
  The FOCAS integration fixture now needs just two things running
  together:
    1. A single focas-mock container listening on :8193 (one service,
       no per-series compose profile ceremony — the mock's native
       FOCAS Ethernet responder handles every call the managed driver
       issues).
    2. The integration-test assembly built. The managed
       `WireFocasClient` dials the mock directly; there is no shim
       DLL, no P/Invoke, no test-bin DLL copy step.
  This script handles both and cleans up on exit.

  Designed to run unattended on a build agent or on a developer box.
  Exit code matches the test suite (0 = all pass or skip-clean,
  non-zero when any integration test failed).

.PARAMETER Profile
  focas-mock profile name to seed at startup (e.g. `ThirtyOne_i`,
  `Sixteen_i`, `fwlib30i64`). Defaults to `ThirtyOne_i`. The fixture
  resolves aliases via `FocasCncSeries`, and tests that need per-series
  state can call `fixture.LoadProfileAsync` directly at test start to
  override the default.

.PARAMETER SkipDocker
  Skip docker up/down. Use when the mock is already running from
  another shell.

.PARAMETER Configuration
  Build configuration — Debug or Release. Default: Debug.

.PARAMETER KeepDocker
  Don't tear down the docker stack on exit. Useful for iterating on
  tests.
