fix: report time in Brian's local timezone, not UTC

clock.stamp() (injected into her chat prompt via _now_note, and into reflection)
rendered UTC and ignored the configured timezone, so 'what time is it' answered in
UTC — hours off from his actual time, reading as 'she doesn't know the time'. Now
converts to config.timezone (America/New_York -> EDT/EST), UTC fallback if the zone
can't load. Storage stays UTC; this only changes what she reads.
