Summary

This PR includes several code quality improvements to enhance type safety and logging practices:

• Add missing return type annotations to openhands/io/json.py
• Add missing return type annotation to openhands/memory/view.py
• Replace print() statements with proper logging in tests/e2e/test_settings.py

Changes

1. Type hints in openhands/io/json.py

• Add return type annotation -> str to dumps() function
• Add parameter type annotation : str and return type -> Any to loads() function
• Import Any from typing module

2. Type hint in openhands/memory/view.py

• Add return type annotation -> Iterator[Event] to __iter__() method
• Import Iterator from collections.abc

3. Logging improvements in tests/e2e/test_settings.py

• Replace all print() statements with proper logging using logger.info(), logger.warning(), and logger.error()
• Add logging module import and create logger instance
• Follows best practices for test logging and enables better log management

Testing

The changes are minimal and focused:

• Type annotations don't affect runtime behavior
• Logging changes maintain the same information output but use proper logging infrastructure
• All existing tests should continue to pass

Checklist

• Code follows the project's style guidelines
• Changes are backward compatible
• No breaking changes introduced
