Description: Summary Add an "Add run metadata" toggle to the Start block (under Show additional fields, default off) exposing a server-injected object: userEmail, workspaceId, workflowId, executionId, executionType, executionMode, startTime Every field describes the invoking run — inside a custom block they're the consumer's email/workspace/workflow, so the published workflow can trust who called it The metadata key is server-owned when the toggle is on: caller-supplied values are stripped and overwritten, an input format field named metadata fails fast, toggle-off behavior is byte-identical Actor email resolves via one lazy user lookup in executeWorkflowCore; child/custom-block metadata is built at the invocation boundary in workflow-handler Type of Change New feature Testing Unit tests for spoof-override, fail-closed, and name-collision behavior + tag-dropdown schema paths + custom-block caller identity. Lint, typecheck, and check:api-validation:strict pass. Checklist Code follows project style guidelines Self-reviewed my changes Tests added/updated and passing No new warnings introduced I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)
