Technotes carry a C card (Fossil's timeline title) but the fold dropped it, so the timeline and listing showed raw 40-hex event ids — libfossil's real technotes read 'Technote: 0a83aac2...' instead of 'Project milestone: merge feature ported in'. Fold the comment, prefer it in the timeline and listing, and add it additively (ALTER, not a rebuild) for indexes created by the older schema. Also corrects a stale '-- C card' note on forum_post.body, which is the W card. check-in: 254d554df8 user: dmestas tags: trunk
