Regenerate daily summaries when new sessions are added
Previously, daily summaries were only generated for dates without any
summary. If new sessions were processed for a date that already had a
summary, the summary would become stale.
Now the process command tracks which dates had new sessions and
regenerates summaries for those dates, ensuring the daily view
stays up to date.
