Describe the bug
For some reason Nitro does not transpile libraries from external registry such as JSR even though its build output is supposed to be standalone. I am trying to use @std/ulid from JSR but in runtime Nitro cannot find it.
Also see https://github.com/nuxt/nuxt/issues/30737

Research direction
Start with the linked reproduction and inspect the generated entry point at /app/server/chunks/routes/api/ulid.get.mjs, focusing on the runtime failure to resolve @std/ulid. Reproduce the deployment and verify that the standalone Nitro output can load @std/ulid from JSR without the Cannot find package error.
