`Vercel Microfrontends` routing now covers `vc alias` and branch domains

Aliases now keep full microfrontend routing, not just deployment IDs. Branch domains also route across matching branches in sibling projects, useful only if your app is already split this way.

[ KEY POINTS ]
  1. vc alias now preserves the full routing config from the source deployment, reducing preview/prod mismatch after aliasing.
  2. Branch-assigned project domains now route to the same branch across every project sharing that branch name inside the microfrontend.
  3. Requires the latest Vercel CLI; old CLI behavior can keep routing assumptions stale during deployment workflows.
  4. Niche but practical for multi-app Next.js setups. Single-project Vercel apps get almost no benefit.
