`WorkflowRunButton` is its own button built on the Base UI `Button` primitive, so it leaves your shadcn `Button` alone. It reads Run workflow, then Stop with a ring that fills with `progress`, then Run again.

| `phase` | | `idle`, `running` or `done`. |
| `progress` | `0` | From 0 to 1. |
| `onPlay` | | Called from idle and done. |
| `onStop` | | Called while running. |
