What would you like to be added:
Improved code quality, documentation, and maintainability across multiple packages in the Kruise project by:

1. Fixing typos in TODO comments (e.g., "indenpent" → "independent", "imp" → "implement")
2. Improving TODO comment clarity and formatting for better developer guidance
3. Replacing hardcoded values with named constants for better maintainability
4. Enhancing documentation for future configurability options
5. Fixing improperly formatted TODO comments
6. Improving comments for skipped tests and future implementations
7. Adding better context to existing TODO comments

Why is this needed:
These improvements are needed to:

• Enhance Developer Experience: Clearer, more accurate TODO comments help developers understand what needs to be done and why
• Improve Code Maintainability: Named constants instead of magic numbers make the code more readable and easier to modify
• Better Documentation: Enhanced comments provide better guidance for future development and contributions
• Code Quality Standards: Fixing typos and improving formatting maintains high code quality standards
• Onboarding: Better documentation helps new contributors understand the codebase more quickly
• Future Development: Clear TODO comments help prioritize and plan future enhancements
