Set up and use the tfe_outputs data source to share state across HCP Terraform workspaces

Steps

1. In the producing workspace, ensure outputs are defined in the Terraform configuration; they are automatically available to other workspaces in the same HCP Terraform organization.
2. In the consuming workspace's Terraform configuration, declare a tfe_outputs data source block with the organization and workspace name of the producing workspace.
3. Reference specific output values with data.tfe_outputs.<name>.values.<output_name> in the consuming module; the data source reads the current state outputs of the producing workspace.
4. Ensure the token used by the consuming workspace has read-state permission on the producing workspace; use a team API token with the appropriate permissions rather than a personal token for CI.
5. Avoid using terraform_remote_state for cross-workspace sharing in HCP Terraform; tfe_outputs is the recommended approach and avoids exposing the full state file to the consuming workspace.
6. Configure a run trigger from the producing workspace to the consuming workspace so the consumer re-plans automatically when the producer's outputs change.
