Microfrontends routing now applies to vc alias and branch domains

Vercel now applies microfrontends routing to vc alias and branch domains, ensuring consistent routing behavior across preview environments.

Vercel has extended its microfrontends routing capabilities to support custom alias domains (via vc alias) and Git branch-specific preview domains. Previously, complex multi-project routing rules were often limited to production domains. This update ensures that developers can seamlessly test federated frontend architectures in preview environments before merging.

Vercel has recently rolled out an important upgrade to its support for microfrontend architectures on the platform. Now, microfrontend routing rules will automatically apply to alias domains created via the `vc alias` command, as well as to preview domains (Branch Domains) automatically generated based on Git branches.
