Summary

AI summary

Fixed introspection bundle writing to wrong directory causing import failures.

Full changelog

Fixed

Introspection bundle written to wrong directory —
unIntrospection()\ (used by both \urb validate\ and \urb deploy) wrote the esbuild bundle to \os.tmpdir(). When the bundled server executed \utoDiscover(registry, new URL('./agents', import.meta.url)), \import.meta.url\ resolved to the temp directory, causing relative paths like ./agents\ to point to non-existent locations. The bundle is now written adjacent to the original entrypoint (\dirname(absEntry)/.vurb-introspect-{ts}.mjs), preserving correct \import.meta.url-relative resolution. Affected files: \introspect.ts, \deploy.ts.
