* [refactor] move workflow domain to its own folder
* [refactor] Fix workflow platform architecture organization
- Move workflow rendering functionality to renderer/thumbnail domain
- Rename ui folder to management for better semantic clarity
- Update all import paths to reflect proper domain boundaries
- Fix test imports to use new structure
Architecture improvements:
- rendering → renderer/thumbnail (belongs with other rendering logic)
- ui → management (better name for state management and UI integration)
This ensures proper separation of concerns and domain boundaries.
