WHAT IT DOES

What toggl_stop_time_entry does on Tempus MCP

WHY IT NEEDS A POLICY

Why toggl_stop_time_entry needs a policy

Stopping a time entry modifies its state (marks it as ended/completed) in Toggl Track. This is a reversible write operation — the time entry still exists and could potentially be restarted or edited. It does not delete data, execute code, or involve finances. Severity is medium because misuse could disrupt active time tracking records.
