feat: upgrade to v1.2.0 with model param validation and UI improvements

- Upgrade iflow-engine-base to ^2.0.0
- Add sanitizeModelParams for robust model operation validation
- Add try-catch error handling for render mode and model tool calls
- Preserve tree scroll position across tab switches
- Optimize tree node reveal with visibility check and centered scrolling
- Refactor collectModelParams to support multi-model grouping
- Fix tree CSS: remove duplicates, constrain overflow, improve layout
- Move version label to bottom-left
- Rebuild demo libs
