When another plugin resolves a specifier and marks it `external: true`,
`CopyModulePlugin::resolve_id` was ignoring the flag and attempting to
`tokio::fs::read` the id, producing `Failed to read copy module <id>`.
This surfaces with `rolldown-plugin-dts`, which returns ambient-module
glob specifiers such as `typeof import("*.jpg")` as external. If `.jpg`
is also configured as `moduleTypes: copy`, the copy plugin (running
`resolve_id` pre) invokes `ctx.resolve` — which runs the dts resolver —
gets back `{ id: "*.jpg", external: true }`, and then crashes trying to
read `*.jpg` off disk.
Fix: check `ResolvedId::external.is_external()` and bail out. The
`AssetModulePlugin` counterpart is not affected because it hooks `load`,
which rolldown skips for external ids.
Added a regression test in `packages/rolldown/tests/builtin-plugin/`
using a user plugin that mimics the dts-plugin behavior.
✅ Deploy Preview for rolldown-rs canceled.
