Feature Request: Show Pomodoro/Stopwatch sessions on Calendar

Would love a setting to show unscheduled tasks I've tracked with the Pomodoro timer or Stopwatch on the Calendar view. Right now, if a task has no date assigned, tracked time only appears in the Focus panel — it's invisible on the calendar.

A toggle (Settings → "Show Pomodoro/Stopwatch sessions on Calendar") that adds tracked sessions as calendar blocks on the day they happened, with the task name and duration would be so amazing!
