  Spectral ruleset enforcing the conventions observed in the Hatchet OpenAPI
  contract (api-contracts/openapi in hatchet-dev/hatchet). The Hatchet API is
  OpenAPI 3.1, uses bearer + cookie auth, namespaces stable endpoints under
  /api/v1/stable, and tags operations by resource (Task, Workflow, Workflow
  Run, Tenant, Worker, Event, Webhook, Rate Limits, API Token, Log,
  Observability, etc.).
