Subject: [PATCH] fix: blurry icon during collapse rotation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. Root cause: parent AppletItemButton sets contentItem.smooth
   = false in Component.onCompleted to fix static icon blur
2. Fix: add Component.onCompleted in ActionToggleCollapseDelegate
   to bind contentItem.smooth to rotation angle via Qt.binding
3. smooth=true during rotation (non 0/180 angles) enables
   bilinear interpolation to eliminate aliasing
4. smooth=false at rest (0/180) preserves original static
   sharpness fix from parent class

Log: Collapse/expand rotation animation no longer blurry

Influence:
1. Verify collapse button rotation animation is sharp
2. Verify static icon remains sharp after animation
3. Verify other tray icons unaffected by this change

fix: 修复折叠图标旋转过程中模糊问题

1. 根因：父类 AppletItemButton 在 Component.onCompleted 中
   设置 contentItem.smooth=false 以修复静止图标模糊
2. 修复：在 ActionToggleCollapseDelegate 新增
   Component.onCompleted，将 smooth 绑定为旋转角度函数
3. 旋转中（非0/180度）smooth=true 启用双线性插值消除锯齿
4. 静止时（0/180度）smooth=false 保持原有静止清晰度

Log: 折叠/展开旋转动画不再模糊

Influence:
1. 验证折叠按钮旋转动画过程中图标清晰
2. 验证动画结束后静止图标保持清晰
3. 验证其他托盘图标不受影响
