OpenAPI Spec Not Accessible

[ryanwaits]

Describe the bug

The openapi.json file is no longer accessible at stacks-blockchain-api.vercel.app/openapi.json after the Fastify migration. We are using this to automatically keep API references up-to-date in our documentation repo.

Current Behavior

• Other APIs successfully serve their OpenAPI specs:
  • ✅ ordinals-api.vercel.app/openapi.json
  • ✅ runes-api.vercel.app/openapi.json
  • ✅ token-metadata-api.vercel.app/openapi.json
  • ❌ stacks-blockchain-api.vercel.app/openapi.json

Likely Cause

OpenAPI files are being written to ./docs instead of ./tmp or ./public, preventing Vercel from serving them correctly.
