Pranay Prakash 543f481a79 feat(core): capture workflow runtime in executionContext + OTel span
- start(): always record the resolved runtime (node-vm | quickjs) on the run's
  executionContext (defaulting to node-vm), so every run captures which runtime
  it uses and the choice is pinned per-run.
- runtime.ts: tag the workflow execution span with `workflow.runtime`
  (Attribute.WorkflowRuntime), resolved per-invocation via useQuickJSRuntime so
  it's authoritative on resumes — for both the node:vm and QuickJS paths.
