境界が同じでも5秒ごとに変更通知を出し、マーカーJSONを再書込みする問題を修正します。境界の値比較と深いスナップショット保持に加え、同world・同座標の位置更新を抑止します。world移動は旧worldの削除通知と新worldの更新通知を行います。
単独検証JAR:
3.9-SNAPSHOT-acecore-issue1-bc46383e、SHA-25646d0be1b349c368382e601ddd0b01b67eac2d1d9cc51df646a1cdeeb967bfb90。統合検証ソースは公開済み
6caa618f(PR #5/#6)とbc46383e(本PR)の組み合わせです。比較は新規ワールド・独立filetree保存先で実施しました。ファイル世代数をR2のPutObject回数や料金とは扱いません。本番R2の計測・本番導入・一般向けバイナリ公開は別判断です。
このPR単独の基点にはCI workflowがないため、PR #5/#6を含む統合検証結果を併記しています。
