fix(afterburn): improve test coverage and exclude generated files from coverage

- Add comprehensive test coverage for afterburn package exports and functionality
- Add package-specific vitest config with 70% coverage threshold
- Exclude generated files from coverage checks globally
- Fix CI test failures by achieving sufficient coverage for all afterburn functionality
- Replace private API testing with proper public API testing
