//! The app's vite is imported the way Node's `import("vite")` finds it: the
//! `import` condition of its exports. Vite 5 and 6 map `require` to a CJS
//! proxy exporting little more than `defineConfig`, which `require.resolve`
//! picked: the host then saw no `version`, `resolveConfig` or `parseAst`. Here
//! a plugin reports the `this.meta.viteVersion` the host read from vite.
