/**
* Retires the v1 hand-written UI shells once the generated stubs can take
* over (ADR 0023):
*
* 1. Rewires `ui/rsbuild.config.ts` so the client build entry, the
*    `./Hydrate` federation expose, the SSR build entry, and the server
*    `./Router` expose all point at the generated stubs
*    (`hydrate.gen.tsx` / `router.server.gen.tsx`) instead of the
*    hand-written shells.
* 2. Deletes each retired shell only when its generated replacement exists
*    AND no build config reference remains — they are live build entries on
*    a v1 tree, so both guards are required.
*
* The generated stubs import `everything-dev/ui/hydrate` /
* `everything-dev/ui/router-server` / `everything-dev/ui/entry`, which are
* only published by v2 framework releases. The apply train pins the v2
* catalog (migrate-pnpm) before this step, so resolution succeeds after
* the post-apply install.
