v1.6.0 — the per-point stream

One record per committed point on every SDK surface, keyed by the per-match gapless seq. REST: getMatchPoints / iterateMatchPoints, covers_from_start on the page. Native streamer: point frames now yielded as PointUpdate instead of being dropped. Push streamer: points: true subscribes the point channels from the mint's vocabulary, pointsResume (default on) REST-catches-up every tracked match on each (re)connect, dedups by seq, fills mid-stream gaps before the trigger frame, and bounds the cursor set (404-prune + 2h idle expiry). RankingSystem gains 'elo' + companion params on listRankings. See CHANGELOG for full detail.
