Implement the 'wslc container prune' command to remove all stopped containers. The backend IWSLCSession::PruneContainers API already exists; this adds the CLI frontend. Changes: - ContainerPruneCommand: new command class with --session arg - ContainerService::Prune(): service layer using RAII PruneResult - PruneContainers task: prints pruned container IDs and reclaimed space - PruneContainersResult model struct - 3 localization strings (desc, long desc, space reclaimed) - CLI parsing unit tests in CommandLineTestCases.h - E2E tests: help, no-stopped, stopped, running-preserved, multi-stopped - Updated container help output test to include prune subcommand Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Since it's zero reclaimed, can we use the .Verify({.Stdout = "...: 0", ...}); instead?

Is there a chance we can hardcode the values here based on manual test, or they are unpredictable?

Unless my comment suggestion above does not help eliminate the need for this method, I would suggest moving this method to the WSLCExecutor where another method called StdoutContainsLine method exist.

Implementation looks good; have same feedback as Amir regarding some of the test code.
