Pull request overview

This PR integrates the Node.js Hosting Public API into the Rust CLI by adding a new hosting nodejs command group backed by a dedicated HTTP client, and by vendoring/embedding the API’s OpenAPI spec into the CLI’s API catalog so it’s discoverable via the API explorer workflow.

Changes:

• Added a new hosting module with a nodejs command group for managing Node.js PaaS apps (apps, deployments, source upload, secrets, logs).
• Introduced a Node.js Hosting REST client (reqwest) plus tests, and added OAuth scope constants for the new API.
• Vendored the OpenAPI spec and wired it into the API catalog generation + API explorer (including a helper script to refresh the spec).
