Set weekly Thursday 7AM shift flag for rotation

Your shift rotation marker isn't updated reliably, causing manual toggles, missed on-call handovers. It updates the rotation marker so coordinators and schedulers see the correct state before Thursday 7am.

Overview

Eliminate last-minute manual shift toggles by automatically writing the active rotation flag every Thursday at 7am. Coordinators and scheduling tools will consistently reflect the correct on-call state before the shift, reducing handover errors and tool mismatch.
