[18202781743]

1. Remove unused QDebug include from sunrisesunset.cpp
2. Cache date.startOfDay() to avoid redundant computation
3. Remove debug qInfo logging of raw sunrise/sunset calculations
4. Add detailed structured logging when auto theme change is triggered
5. Log includes theme transition, current time, coordinates, UTC offset,
   sunrise and sunset times

The changes reduce unnecessary debug output while adding more
informative logging at the point where theme changes are actually
applied, making it easier to diagnose auto-theme behavior.

Log: Improved auto theme switching diagnostics with detailed change
logging

Influence:

1. Verify auto theme switching still works correctly at sunrise and
   sunset boundaries
2. Confirm theme change logs contain accurate timestamps, coordinates,
   and theme names
3. Test behavior across different UTC offsets and extreme latitudes
4. Ensure no functional regression from removing the debug log line in
   sunrise/sunset calculation
5. Verify sunrise/sunset datetime values remain correct after
   refactoring startOfDay caching

refactor: 改进主题管理器日志和日期处理

1. 移除 sunrisesunset.cpp 中未使用的 QDebug 头文件
2. 缓存 date.startOfDay() 避免重复计算
3. 移除日出日落原始计算的调试日志
4. 在自动主题切换触发时添加详细的结构化日志
5. 日志包含主题切换、当前时间、坐标、UTC 偏移、日出和日落时间

这些改动减少了不必要的调试输出，同时在主题实际切换处添加了更有信息量的日
志，便于诊断自动主题切换行为。

Log: 通过详细的切换日志改进自动主题切换诊断能力

Influence:

1. 验证自动主题切换在日出和日落边界仍能正常工作
2. 确认主题切换日志包含准确的时间戳、坐标和主题名称
3. 测试不同 UTC 偏移和极端纬度下的行为
4. 确保移除日出日落计算中的调试日志未造成功能回归
5. 验证重构 startOfDay 缓存后日出日落时间值仍然正确

Summary by Sourcery

Improve automatic theme switching diagnostics while simplifying sunrise and sunset date calculations.

Enhancements:

• Improve automatic theme-switch diagnostics with structured logs that record the theme transition, current time, location, UTC offset, sunrise, and sunset.

Chores:

• Reduce sunrise/sunset calculation noise and streamline date handling by removing unused logging support and reusing the day-start timestamp.

Reviewer's Guide

The PR refactors sunrise/sunset datetime calculation to reuse a cached start-of-day value and removes noisy raw-calculation logging, while adding a detailed ISO-formatted diagnostic record immediately before each automatic theme transition is applied.
