refactor: update TypeScript configuration and test utilities for improved type safety

- Modify tsconfig.json to relax strict type checking for gradual migration
- Update test files to use more flexible type checking and mocking
- Add type-safe mock and test utility functions
- Improve error handling and type inference in test suites
- Export Tool interface and tools list for better testing support
