- Added comprehensive test cases for modifying tasks, including editing points for chores, kindness acts, penalties, and rewards in `task-modified.plan.md`.
- Ensured all tests are isolated and run in serial mode to maintain state integrity.
- Introduced a dual-token system for user authentication: a short-lived access token and a long-lived rotating refresh token.
