…tion and auto-detection

WSL Containers (wslc) runs dockerd inside a lightweight VM that exposes no
Windows named pipe or TCP port; the only host-visible channel is the stdio
bridge `wslc system session run docker system dial-stdio`. This adds first-class
wslc support to docker-java.

Transport (docker-java-transport, -transport-httpclient5):
- WslcSocket: a Socket whose streams are the wslc dial-stdio child process
  (mirrors NamedPipeSocket; java.util.logging only, no new dependency).
- ApacheDockerHttpClientImpl: a `wslc` scheme case plus a WslcSocket branch.
  Hijacked exec/attach/log streams work unchanged at the HttpClient5 socket level.

Lifecycle integration (docker-java-core):
- wslc's Windows integration (127.0.0.1 port relay and Windows-path bind mounts)
  is wired by the wslc control plane only when a container is created/started
  through the native `wslc` CLI, not over the Docker API on the same dockerd.
- WslcLifecycleDockerHttpClient decorates a Docker-API client and reconciles just
  the affected calls with the wslc CLI, delegating everything else unchanged:
  POST /containers/create -> wslc create, POST /containers/{id}/start -> wslc
  start (wires relay+bind), POST /networks/create -> wslc network create, and
  GET /containers/{id}/json with NetworkSettings.Ports overridden from `wslc list`
  (the start relay's real host port differs from the daemon's recorded one).
- Activated transparently in DockerClientImpl.getInstance only when the host
  scheme is wslc, so unix/npipe/tcp are unaffected and no extra dependency is
  needed. Consumers that shade docker-java-core (e.g. Testcontainers) pick it up
  after a plain rebuild.

Auto-detection (DefaultDockerClientConfig):
- when DOCKER_HOST is unset, fall back to wslc://localhost on Windows only if the
  //./pipe/docker_engine pipe is absent and wslc is available (`wslc version`
  exit 0, WSLC_EXECUTABLE-overridable), so Docker Desktop/Podman keep winning.

Tests run without a daemon or wslc CLI: WslcSocketTest (executable resolution and
connect failure) and WslcLifecycleDockerHttpClientTest (request pass-through,
inspect fallback when wslc is unavailable, create-failure handling).
