Backend:
- Add before_seq + limit params to list_messages
- When limit set without after_seq, ORDER BY DESC then reverse (gets latest page)
- Reject after_seq + before_seq together (400)
- Cap limit at 1000, no default change (CLI compat)
Frontend:
- Initial load fetches ?limit=100, scrolls to bottom
- Scroll near top triggers ?before_seq=lowestSeq&limit=100
- useLayoutEffect maintains scroll position after prepend
- Gap repair loops after_seq fetches until caught up
- Auto-scroll only when near bottom (doesn't yank while reading)
- "loading older..." and "beginning of conversation" indicators
