0.7.3 - agents now know today's date and time

[0.7.3] - 2026-10-29

Fixed

• The agents now know today's date and time (in TIMEZONE). Before, "today's news" searched around the model's
  training date, and to find out the date the bot asked to run Python code. The router and every team and agent
  get the current date and time in their system prompt (a few tokens per call); Coder and Analyst are told not to
  run code to get them.
