- Add create_member_with_cycles helper that uses fixed 'today' date
- Update tests to use explicit 'today:' option instead of Date.utc_today()
- Prevents test failures when current date changes (e.g., in 2026+)
- Tests now explicitly delete and regenerate cycles with fixed dates
- Ensures consistent test behavior regardless of execution date
- Change algorithm to start from last existing cycle instead of start_date
- Deleted cycles (gaps) are no longer automatically filled
- Add test to verify gaps remain unfilled
- Update documentation to clarify gap handling behavior
- Replace weak assertions (>= 0, if length > 0) with concrete expectations
- Remove unnecessary Process.sleep calls (tests run synchronously)
- Add get_member_cycles helper for direct cycle verification
- Tests now validate actual generated cycles instead of relying on async behavior
