Summary

AI summary

Fixed crash when native addon isolated-vm was present during esbuild bundling.

Full changelog

Fixed

Native addon bundling crash — \urb validate\ and \urb deploy\ introspection builds failed when \isolated-vm\ (an optional peerDependency used by \SandboxEngine) was present in the dependency tree (e.g., via
pm link\ during development). esbuild cannot bundle .node\ native binaries. Added \external: ['isolated-vm']\ to the introspection esbuild config in both \introspect.ts\ and \deploy.ts. This is not a breaking change — \isolated-vm\ is lazy-loaded via
equire()\ with a try/catch fallback.
