fix(tests): resolve test configuration and import issues

- Fix Jest configuration for langchain to use correct tsconfig path
- Update test imports from 'bun:test' to '@jest/globals'
- Fix type errors in test configurations (use objects instead of false)
- Simplify test configurations for smolagents and mcp-use packages
- Set rootDir correctly for typescript subdirectory structure
