Restrict the Vite+ mock to the intended lookup.

Line 21 checks only _cwd. Any getPkgJSON call under /vite-plus receives Vite+ metadata, even when it requests another package or uses another via path. This can make unrelated tests pass with incorrect package data. Check pkg === 'vite' and options?.via?.includes('@nuxt/vite-builder') before returning this object.

Proposed fix

- if (_cwd === '/vite-plus') {+ if (_cwd === '/vite-plus'+ && pkg === 'vite'+ && options?.via?.includes('`@nuxt/vite-builder`')) {

more restrictive. The if statement checking _cwd === '/vite-plus' should also
validate that pkg === 'vite' and that options?.via includes '`@nuxt/vite-builder`'
