Pull request overview

Updates the Nitro CLI and client to list a client’s published versions via the new Client.publishedVersions GraphQL field, aligning the CLI command with a dedicated backend API instead of deriving published versions from the full versions list.

Changes:

• Add Client.publishedVersions(stage: ...) support to the Nitro GraphQL client (operation + client interface/implementation).
• Update nitro client list published-versions to require --stage and to display publishedAt instead of createdAt/stages.
• Refresh the embedded GraphQL schema and persisted operations to include the new fields/types.
