Summary

This patch introduces a build failure for services attempting to use the Edge Runtime, which is currently unsupported for services.

Services explicitly configured to use the Edge Runtime (`config.runtime = 'edge'` or `'experimental-edge'`) will now fail the build with an `EDGE_RUNTIME_UNSUPPORTED_IN_SERVICES` error instead of being silently built as a Node function.

If your service was previously using an Edge Runtime configuration, remove `config.runtime = 'edge'` or `config.runtime = 'experimental-edge'` from the service entrypoint configuration to allow it to build as a standard Node function.
