isActive() for book/game/comic only checked for a resolved id, so a
note that had run resolve() but never a real sync() (no read_status/
play_status/status field yet) was treated as static and never
enriched on subsequent runs. Now also requires the status-analog
field canonical render always writes; missing it means sync() hasn't
actually produced output yet.
- render **Rating:** line in manga/book/game/comic body (after read/play
status, gated on rating != '0' + stars non-empty), matching watchlist's
render.ts convention
- manga finish-flip now notifies user (final chapters out), matching
chapter-flip's existing notify path
- game renderGame emits ## Links (Steam by appid, RAWG by url) — fixes
latent owned-heading strip where user-added Links sections silently
vanished since games never re-rendered the heading
- move duplicated deriveReadStatus/deriveRating/parseNumOrNull into
library/convert.ts, import across specs; zero behavior change
