Pull request overview

Adds a new bootstrap-gcp cleanup CLI subcommand to delete OMS-bootstrapped GCP projects (optionally cleaning up OMS-created DNS records), aiming to remove the need for manual teardown.

Changes:

• Add oms beta bootstrap-gcp cleanup command with --project-id, --force, and --skip-dns-cleanup flags.
• Label newly created GCP projects with oms-managed=true and add client methods to verify/delete OMS-managed projects and delete OMS DNS records.
• Add docs and initial test scaffolding for the cleanup functionality.
