Pull request overview

Adds --entrypoint handling to the WSLC container create/run path, enabling callers to override the container init executable and validating behavior via new end-to-end tests.

Changes:

• Parse --entrypoint from CLI args into ContainerOptions.
• Pass ContainerOptions.Entrypoint into WSLAContainerLauncher when creating containers.
• Add new e2e coverage for entrypoint scenarios (success, args forwarding, invalid path, detach lifecycle) and ensure Debian test image cleanup.
