fix: restore colors in CLI help output and use Node's resolution algorithm for workshop-app

- Add colors back to interactive keys display in yargs epilogue
- Use import.meta.resolve() for finding workshop-app package instead of manual path resolution
- Update example/epicshop/package.json to include @epic-web/workshop-cli dependency
- Fixes GitHub Actions playwright tests that were failing due to missing CLI
