/**
 * #12362 WI-7 residual — the LifeOps `dispatch_workflow` workflow step drives
 * a REAL embedded workflow execution end to end.
 *
 * The subject under test is the seam between the two workflow layers: a
 * LifeOps owner-workflow step (`kind: "dispatch_workflow"`, contributed by
 * plugin-personal-assistant's default WorkflowStepRegistry pack) resolves the
 * REAL `WORKFLOW_DISPATCH` service and lands a row in the REAL
 * `workflow.embedded_executions` table (PGlite-backed EmbeddedWorkflowService).
 *
 * The step is invoked exactly the way the LifeOps dispatcher
 * (`WorkflowsDomain.executeWorkflowDefinition`,
 * plugin-personal-assistant/src/lifeops/domains/workflows-service.ts) invokes
 * it: registry bound to the runtime → `registry.get(step.kind)` →
 * `paramSchema.parse(step)` → `contribution.execute(validated, args, ctx)` —
 * NOT by calling the dispatch service directly. The full `WorkflowsDomain`
 * class is not importable here (its repository pulls built dists of
 * plugin-browser/finances/inbox), so this file drives the registry seam the
 * dispatcher consults; the loop mechanics around that seam are covered by
 * plugin-personal-assistant/test/workflow-step-registry.test.ts.
 *
 * Cases:
 *   (a) dispatch_workflow step → real execution row; the parent run's
 *       request + accumulated outputs are threaded into the nested
 *       execution's triggerData (the contribution's contract)
 *   (b) idempotent double-fire: same payload `__idempotencyKey` collapses two
 *       step executions onto one embedded execution row
 *   (c) WORKFLOW_DISPATCH not registered → structured failure, no execution
 *   (d) unknown workflowId → structured failure from the real dispatch, no row
 *   (e) malformed step (no workflowId) fails schema validation before dispatch
