WHY IT NEEDS A POLICY

Why stop_time_tracking needs a policy

Stopping time tracking writes/updates the task's time log by ending the active session. This is a reversible modification (time tracking could potentially be restarted), placing it in the Write category rather than Destructive. Misuse could corrupt time records used for productivity analysis or billing, giving it medium severity.

From the tool's definition 'Stop time tracking for a specific task' — terminates an active time-tracking session, modifying the task's time record
