* feat(api): purge Cloudflare CDN before and after OpenAPI spec upload Purge api.cdn.clsrio.com edge cache for openapi-latest and the dated spec URL so deploys are not blocked by the 1h Cache-Control TTL on R2 objects. Uses the same CLOUDFLARE_API_TOKEN and CLOUDFLARE_ZONE_ID pattern as embed uploads; skips when credentials are unset. Co-authored-by: Rotimi Best <rotimi-best@users.noreply.github.com> * fix(api): purge OpenAPI CDN cache only after upload Match the embeds upload pattern: update R2 first, then invalidate edge cache so clients refetch the new spec. Co-authored-by: Rotimi Best <rotimi-best@users.noreply.github.com> * fix(api): treat Cloudflare purge 2xx as success when body is unparseable Avoid false upload failures when the purge API returns 200 with a non-JSON body.
