chore: migrate project to Bun testing framework and update configuration

- Replace Jest with Bun's native testing framework
- Update test configuration and utilities to support Bun test environment
- Add mock implementations for SSE and security testing
- Refactor test setup to use Bun's testing utilities
- Update package dependencies and scripts to align with Bun testing
- Enhance type definitions for Bun test mocking
