Support asset relocation like `@vercel/ncc` ?

Could you please support asset relocation feature like `@vercel/ncc`? https://github.com/vercel/webpack-asset-relocator-loader#how-it-works

`@vercel/ncc` could support `path.join()` asset been copied to dist directory. Would you please also support this feature ?

Thanks.

Start by reviewing tsup's existing asset handling and the linked webpack-asset-relocator-loader behavior. Define expected handling for path.join() assets and verify that matching assets are copied to the dist directory; the issue names no source file or test.
