@copilot resolve the merge conflicts in this pull request

Merge conflicts resolved in commit f101144. The conflicts in README.md and labs/README.md were resolved by adopting origin/preview's updated package names (azure-containerapps-sandbox, SandboxGroupClient), ACA CLI install URL, lowercase plugin name, and shell references, while preserving our DTS Workflows lab row and DTS-specific setup notes.
