Deploy a new blockchain node. Call get_deployment_options first for valid IDs.
Trader nodes are region-bound (e.g., London, Ashburn, Singapore). Always confirm
the region with the user before deploying — region cannot be changed after deployment.
Args:
name: Node name.
project: Project ID from list_projects (e.g., PR-123-456-789).
blockchain: Blockchain ID from get_deployment_options (e.g., BC-000-000-008).
cloud: Cloud ID from get_deployment_options (e.g., CC-0016 for Global, CC-0020 for London).
