/**
 * Vite plugin that runs auto-detection in its async `config` hook, then
 * mutates `userOptions.clientPackages` so all downstream consumers (the
 * transformer's whitelist filter, `resolveUserConfig`'s noExternal merge)
 * see the merged list when their own hooks read it.
 *
 * Why mutation: the orchestrator passes the same `userOptions` reference
 * to every plugin it creates. As long as nobody copies the object on the
 * way through, mutating `clientPackages` here is visible in every other
 * plugin's hooks. See `createPluginOrchestrator.{server,client}.ts` for
 * the comment guarding against accidental spreads.
 *
 * `enforce: "pre"` puts this plugin's `config` hook ahead of
 * `createEnvironmentPlugin`'s, so by the time `resolveUserConfig` reads
 * `userOptions.clientPackages` for the noExternal merge, the auto-detected
 * packages are already in the list.
 *
 * Returns a partial Vite config that adds the merged list to the **root**
 * `optimizeDeps.exclude`. The per-environment SSR-side exclude in
 * `resolveUserConfig` covers `srrConfig.optimizeDeps.exclude` only — that
 * never reaches Vite's dev pre-bundler, which reads from the root config.
 * Without this, esbuild concatenates every `"use client"` directive out of
 * each clientPackage submodule into `node_modules/.vite/deps/<pkg>.js`, the
 * server-env module runner consults the same cache when resolving the
 * package, and vprs's transformer never sees the directives to convert
 * them into `registerClientReference` — a server component importing
 * `@chakra-ui/react` (or any other auto-detected client package) then
 * crashes the dev server with `react does not provide an export named
 * createContext` under the `react-server` condition.
