Subject: [PATCH] fix: reset partialFactor in C++ exit path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. Add qFuzzyCompare guard to reset m_partialFactor in exit()
   consistent with updatePartialFactor() style
2. Remove invalid QML assignment to read-only partialFactor
   property in MultitaskviewProxy.qml
3. Update copyright year in MultitaskviewProxy.qml to 2024-2026
   as required by SPDX CI check

Influence:
1. Test multitaskview exit resets partialFactor without QML errors
2. Verify gesture exit flow works correctly with factor reset

fix: 在C++退出路径中重置partialFactor

1. 在exit()中添加qFuzzyCompare守卫重置m_partialFactor
   与updatePartialFactor()风格保持一致
2. 删除MultitaskviewProxy.qml中对只读partialFactor
   属性的无效赋值
3. 更新MultitaskviewProxy.qml版权年份为2024-2026
   以满足SPDX CI检查要求

Influence:
1. 测试多任务视图退出时partialFactor正常重置且无QML报错
2. 验证手势退出流程中factor重置的正确性
