 * Generate Orval client into api/generated/.

 * OpenAPI source priority:
 * 1. Sibling Nest package (`../ghabilee-backend` or `../backend`) via `generate:openapi`
 * 2. Committed `./openapi.json` (CI, satellite clones, OpenAPI sync PRs)
 *
 * Live Swagger fetch is intentionally not used — clients stay in sync via
 * ghabilee-backend's `sync-openapi-clients` workflow.
