test: migrate test suite from Jest to Bun test framework
- Convert test files to use Bun's test framework and mocking utilities - Update import statements and test syntax - Add comprehensive test utilities and mock implementations - Create test migration guide documentation - Implement helper functions for consistent test setup and teardown - Add type definitions for improved type safety in tests
