"""Full-night digester: detail EVERY session that contains a mission.

digest.py only detailed the last 3 sessions, which is wrong for the end-of-night
files (25 sessions, with the two bad matches in the middle and the clean
3-player matches at the end).  A session is detailed if it contains any
death/respawn/damage marker; menu-only sessions collapse to one line.
