Subject: [PATCH] perf(payload): fast-path idle dimensions + scoped ownership
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

补充上一版按维度精细化独占：
- MainThreadPhaseCoordinator.runScoped 加快速路径：涉及维度当前都没在 tick 时，
  直接执行 action，跳过 hold/cancel/schedule 与 managedBlock 往返。
  多玩家时绝大多数 payload 落在维度空闲窗口，此路径消除其交接开销。
