Lists runners in a scale set.

**Not available yet.** Sylphx Runners is declared in the registry but no backend serves it: every call answers `501` with the problem code `UNIMPLEMENTED`.

- **Path** `GET https://api.sylphx.com/v1/orgs/acme/scale_sets/scale-set/runners`
- **Scope** `runners:read`
- **Effect** `read` — nothing is written.
- **Collection** [runners](/docs/api/runners)
- **Query** `page_size`, `page_token`, `filter`, `order_by`
- **Pagination** the answer carries `runners` and, when there is more, `next_page_token`
