根据本地经纬度和时区计算每日日出日落时刻，自动在 light/dark 主题间切换；跨日出日落临界点修复切换不生效问题。 - apps/electron/src/renderer/lib/solar.ts: 日出日落计算与 solar 模式切换调度 - apps/electron/src/renderer/lib/cities.ts: 内置城市经纬度数据 - apps/electron/src/renderer/atoms/theme.ts: theme atom 接入 solar 切换 - apps/electron/src/renderer/components/settings/AppearanceSettings.tsx: 外观设置新增 solar 模式选项与城市选择 - apps/electron/src/renderer/main.tsx: 启动时初始化 solar 调度 - apps/electron/src/types/settings.ts: 新增 solar 相关设置类型 - apps/electron/src/main/ipc.ts + src/preload/index.ts: solar 相关 IPC 通道

概述
新增「日出日落」主题模式（
themeMode='solar'）。应用自身根据用户选定城市的经纬度与当前日期，离线计算真实日出日落时刻，在日出时切到浅色、日落时切到深色，不依赖操作系统的深浅色切换能力，跨平台行为一致。现有的「跟随系统」模式被动跟随 OS，依赖 macOS / Windows 11 22H2+ 的系统层日落切换，Linux 及更早 Windows 无此能力，且多设备需各自在 OS 层配置。本模式由应用主动按真实天文时刻切换，弥补这一缺口。
改动
types/settings.ts：ThemeMode新增'solar'；AppSettings新增solarLocation?: { lat, lng, name }renderer/lib/solar.ts（新增）：NOAA 日出日落算法（零依赖），导出getSunriseSunset/isDaytime/nextTransition；极昼/极夜返回 null 并 fallbackrenderer/lib/cities.ts（新增）：内置 ~170 个全球主要城市经纬度表 +searchCitiesrenderer/atoms/theme.ts：新增solarLocationAtom与solarIsDaytimeAtom；resolvedThemeAtom增加 solar 分支；applyThemeToDOM增加 solar 分支；initializeTheme加载并监听位置；新增updateSolarLocationrenderer/main.tsx：ThemeInitializer增加 solar 模式每分钟轮询（首次立即执行 +visibilitychange监听，窗口从睡眠/后台恢复时即时刷新），写入solarIsDaytimeAtom驱动resolvedThemeAtom重算，使 diff/toast 等消费方配色同步切换renderer/components/settings/AppearanceSettings.tsx：THEME_OPTIONS增加「日出日落」；新增SolarLocationPicker（城市搜索 + 选择 + 今日日出日落时刻 + 下次切换预览）main/ipc.ts/preload/index.ts：主题设置广播的条件与 payload 增加solarLocation，跨窗口（如 Quick Task 面板）同步位置测试
bun run typecheck全包通过bun run dev启动开发版，设置 → 外观 → 主题模式选「日出日落」→ 选择城市（如北京）→ 验证当前白天切浅色 / 夜晚切深色solarLocation持久化与主题恢复紧急度
常规
备注
Closes #1057
位置获取采用纯手动选城市（零体积、零隐私外发、一次配置）。IP 库自动定位、旅行换网络自动重定位等增强留作后续 PR。
