/**
 * Fastify type-provider-zod emitter for openapi-server.
 *
 * Replaces the hand-rolled Fastify branch in router.ts with a dedicated module
 * that uses fastify-type-provider-zod for request validation and type inference.
 *
 * Key design points (decided, not re-litigated):
 * - createRouter(service) returns a FastifyPluginAsyncZod; mount via app.register(createRouter(service), { prefix })
 * - FastifyPluginAsyncZod carries ZodTypeProvider: no withTypeProvider() call needed inside the plugin
 * - setValidatorCompiler, setSerializerCompiler, setErrorHandler are scoped to the plugin instance
 * - Per route: schema.body, schema.params, schema.querystring, schema.headers, schema.response, config.operationId
 * - preValidation hook for deepObject and delimiter-style query params (emitted per-route, not globally)
 * - Cookie params use manual _ckv safeParse: Fastify 5's FastifySchema only exposes body/querystring/params/headers/response, so there is no cookie slot in the type-provider path
 * - No per-route generic type arguments; req.body/req.query/req.params infer from schemas
 * - No (reply as FastifyReply) casts
