Pull request overview

Adds CLI surface area for container GPU access and init behavior in the Windows wslc toolchain, wiring new flags through argument parsing, models, and container launch flags, and extending E2E coverage and help output.

Changes:

• Add --gpus and --init to container run / container create commands and parse them into ContainerOptions.
• Forward the new options as WSLCContainerFlagsGpu / WSLCContainerFlagsInit when launching containers.
• Add localization entries and update E2E tests (including expected --help output) for both commands.

--gpus sets the flag but nothing in the backend reads it. No DeviceRequests in HostConfig, no handling in WSLCContainer.cpp, IDL still has a TODO. This is a silent no-op. Either wire it up or pull the flag until it works.
