闲言APP — 系统托盘图标生成脚本
创建时间: 2026-06-18
更新时间: 2026-06-22
作用: 用 Pillow 生成 macOS/Windows 托盘图标 PNG + ICO（浅色+深色两套）
设计: 对话气泡 + 三条横线，体现"记录言语"主题
输出:
  - assets/images/tray_icon_light.png  (黑色图标，用于 macOS template + Win 浅色主题)
  - assets/images/tray_icon_dark.png   (白色图标，用于 Win 深色主题)
  - assets/images/tray_icon_light_32.png  (32x32 高清版)
  - assets/images/tray_icon_dark_32.png   (32x32 高清版)
  - windows/runner/resources/tray_icon_light.ico  (黑色图标，Win 浅色主题)
  - windows/runner/resources/tray_icon_dark.ico   (白色图标，Win 深色/纯黑主题)
