feat: add --yes flag for auto-confirmation across multiple workflows

- Enhanced lite-execute, lite-fix, lite-lite-lite, lite-plan, multi-cli-plan, plan, replan, session complete, session solidify, and various UI design commands to support a --yes or -y flag for skipping user confirmations and auto-selecting defaults.
- Updated argument hints and examples to reflect new auto mode functionality.
- Implemented auto mode defaults for confirmation, execution methods, and code review options.
- Improved error handling and validation in command parsing and execution processes.
