Description
Describe the feature
Just migrated from unbuild (with ext: 'js'), I almost forgot to change .[jt]s in the package to .m[jt]s.
If a non-existent file is referenced in the exports` `main` `module` `types of package.json, a warning after building may enhance DX.

Research direction
Start by tracing how package.json fields named in the issue—exports, main, module, and types—are read during the build. Identify the validation or reporting entry point and add coverage for a referenced file that does not exist; done means the build warns about the missing file without changing valid package behavior.
