Add task progress tracking methods documentation and enhance progress update logic

- Introduced a new markdown file detailing task progress tracking methods: manual, weighted, and time-based.
- Updated backend logic to include complete ratio calculations for tasks.
- Improved socket command for task progress updates, enabling recursive updates for ancestor tasks.
- Enhanced frontend components to reflect progress changes based on the selected tracking method, including updates to task display and progress input handling.
- Added support for manual progress flag in task model to facilitate accurate progress representation.
