…r upload in the Vite plugin The Vite plugin decides on `build.sourcemap` in its `config` hook, because Vite warns about `rollupOptions.output.sourcemap`, and maps the decision onto each environment's output directory in `configResolved`. The post plugin that restores debug IDs for `disable-upload` builds is now always present and also stages the source maps for upload.

Part of the stack for #25609. Vite warns about
rollupOptions.output.sourcemap, so the Vite plugin decides onbuild.sourcemapin itsconfighook and maps the decision onto each environment's output directory inconfigResolved, including directories set throughrollupOptions.output.dir. A later plugin that turns source maps off again disables the deletion for that environment.The post plugin that restores debug IDs for
disable-uploadbuilds is now always present and also stages the source maps, after Vite's import analysis has regenerated them.
