[test] Improve shimFiles.test.ts to work with standard dist folder

- Use standard `dist` folder instead of hardcoded `dist-treeshake-*` paths
- Add fallback logic to check multiple dist directory candidates
- Remove local-only comparison test between treeshake-enabled/disabled builds
- Add helper test to verify dist directory is found

This ensures tests work in CI/CD environments where only the standard
`dist` folder exists, while still supporting local debugging builds.
