Cannot use `agents:skills` with wrangler dev.

**Describe the bug**

Because of https://github.com/cloudflare/workers-sdk/pull/13905, I cannot use `vite dev` for now, and `wrangler dev` seems to not recognize `agents:skills` imports, `vite build` with `agents()` plugin still works fine.

**To Reproduce**

Just import `agents:skills` following your docs and try to use wrangler dev instead of vite dev.
