test: Add comprehensive HeroFS API integration tests

- Add tests for all major API endpoint categories
- Implement shared server for performance improvement
- Cover filesystem, directory, file, blob, tools, and symlink operations
- Include tests for CORS and error handling
- Consolidate test setup into a shared module
- Increase test coverage and assertion count
