Fix issues found testing the tools live

- The model has no clock and invented a 2025 start date for the
  calendar; the system prompt now carries the current date and time.
- It also derived a wrong weekday from a date; agenda.py prints the
  weekday itself.
- An announcement ran straight into the answer; a 0.6 s pause follows it.
- The calendar days hint asks for 30 or more when looking for the next
  event.
