背景

#345 新增了托盘图标，但用的是全彩 App 图标：在 macOS 菜单栏里是一块深色圆角方块，颜色突兀、尺寸偏大。

改动

• macOS：改用单色 template 图（trayTemplate.png + @2x，纯黑+alpha），系统自动适配菜单栏深浅外观，不再需要维护两种颜色
• Windows / Linux：没有 template 机制，新增 tray-black / tray-white 两份单色图（16/32px），通过 nativeTheme.updated 跟随系统深浅主题切换
• 原 tray-16/32.png 彩色图保留为加载兜底
• scripts/build-desktop.js 托盘图标存在性校验同步更新

验证

• 真机菜单栏实测：template 图在浅色/着色菜单栏自动反色，视觉重量与系统图标一致
• node --check、npm run test:electron:mcp 通过
