Rama develop · réplica de lectura del repositorio original.

// admin/scripts/merge-openapi.mjs
//
// Deep-merges the public-API OpenAPI document with the admin OpenAPI
// document into a single document for openapi-typescript to consume.
//
// Rules:
//   - paths: union by key; collision throws
//   - components.{schemas,parameters,responses,securitySchemes}: union by name; collision throws
//   - root info, servers, security: public wins (admin's are ignored at the root)
//   - per-operation security on admin paths is preserved untouched
