fix: normalize task IDs to numbers on load to fix comparison issues

- Added normalizeTaskIds function to convert string IDs to numbers
- Applied normalization in readJSON for all code paths
- Fixed set-task-status, add-task, and move-task to normalize IDs when working with raw data
- Exported normalizeTaskIds function for use in other modules
- Added test case for string ID normalization
