HTTP handler paths still use load_tasks/save_tasks for now; ensure they remain functional.

Simulate the race that existed before the fix: two threads concurrently modifying different fields of the same task.

Verify that ``modify_tasks`` uses atomic_json_update under the hood.

Verify that the periodic scanner mutates tasks under the file lock.

Verify that the critical concurrent paths no longer use the racy ``load_tasks()`` + ``save_tasks()`` pattern.

Unit tests for the helper ``_sync_script_symlink``.

Integration tests for the full ``sync_scripts_to_workspaces`` flow.

Verify that ``_update_task_scheduler`` no longer uses the racy ``load_tasks()`` + ``save_tasks()`` pattern.
