Subject: [PATCH] fix(taskmanager): reject invalid drag in onEntered
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

1. Explicitly reject drag events when the dragged app cannot be docked
2. Set drag.accepted to false before resetting dnd state for clarity

Log: Reject invalid app drag in dock taskmanager onEntered handler
Influence: Prevents dock from accepting undockable drags

fix(taskmanager): 在 onEntered 中拒绝无效拖拽

1. 当拖拽的应用无法驻留时，显式拒绝拖拽事件
2. 在重置拖拽状态前将 drag.accepted 置为 false

Log: 在任务栏任务管理器 onEntered 中拒绝无效的应用拖拽
PMS: BUG-370799
Influence: 防止任务栏接受不可驻留的拖拽
