The static import of @sentry/nextjs at module level triggered worker
thread creation even when withSentryConfig was only called in production.
This caused recurring "Cannot find module vendor-chunks/lib/worker.js"
crashes that killed the dev server mid-request.
Fix: replaced static import with dynamic require() inside a
NODE_ENV === "production" block. In dev mode, the Sentry module
is never loaded at all.
