Nest Fastify HEAD Request Middleware Bypass
### Impact In a NestJS application using `@nestjs/platform-fastify`, GET middleware can be bypassed because Fastify automatically redirects HEAD requests to the corresponding GET handlers (if they exist). As a result: - Middleware will be completely skipped. - The HTTP response won't include a body (since the response is truncated when redirecting a HEAD request to a GET handler). - The actual handler will still be executed. ### Patches Fixed in `@nestjs/platform-fastify@11.1.16`
