Summary

Fixed esbuild auto‑install failure by replacing import() with createRequire() to bypass Node.js ESM resolution cache.

Full changelog

Fixed

`@vurb/core` — esbuild Auto-install: ESM Resolution Cache Bypass

createRequire() replaces import() after esbuild auto-install — Node.js ESM caches resolution failures per specifier. After import('esbuild') fails (esbuild not installed), the runtime caches that failure. Even after npm install -D esbuild succeeds, a second import('esbuild') returns the cached error. The fix uses createRequire() from node:module anchored at the project root, which uses CJS resolution and does not cache ESM failures. Applied to both introspect.ts (validate) and deploy.ts.
