fix: review center negative chapter numbers, memory center snapshot display, and range search

- fact-snapshot.ts: chapterLabel() for negative chapter numbers in evidence text

- memory-center.ts: separate chapter/outline snapshots in sorting, chapters first

- memory-center-view.tsx: negative chapter numbers show title; add range search for snapshots
