v0.9.0

🚀 Coding Usage v0.9.0 更新说明 / Release Notes

🇨🇳 中文

• 灵动岛浮层隐藏后不再常驻一个渲染进程：隐藏 30 秒后销毁窗口，下一条告警按需重建。实测释放 113 MB 工作集 / 38–55 MB 私有内存，重建到告警可见约 220 ms；该进程此前会一直挂在后台（JS 堆不足 10 MB，其余全是 Chromium 的单进程底座）
• 修复浮层的首条告警可能丢失：待发告警原来在页面加载完成时回放，此时渲染层还没订阅监听器；改为渲染层就绪（新增 island:ready）后再投递，重建出来的窗口也能收到第一条告警
• 三张按 20px 显示的 Agent 品牌图标改用 128px 源图（原为 512 / 1024px），资源体积 1,020 KB → 62 KB，显示效果不变
• 发布说明的页脚不再只写「Windows」：改为列出 Windows（NSIS / 便携版）、macOS（dmg / zip，含未签名的首次打开提示）与 Linux（AppImage）三平台；本地预览时的 CRLF 也会归一成 LF，与 workflow 生成的正文一致

🇬🇧 English

• The island overlay no longer keeps a renderer process alive after it hides: the window is destroyed 30 seconds after it goes away and recreated on the next alert. Measured: releases 113 MB of working set / 38–55 MB of private memory, with about 220 ms from recreate to a visible alert; the process used to sit in the background for the whole session (its JS heap is under 10 MB — the rest is Chromium's per-process baseline)
• Fixed the overlay dropping its first alert: pending batches were replayed when the page finished loading, before the renderer had subscribed; they are now delivered once the surface reports it is listening (new island:ready), so a freshly created window receives its first alert too
• The three agent brand icons drawn at 20px now ship 128px sources instead of 512 / 1024px ones: 1,020 KB → 62 KB of assets, identical on screen
• The release-notes footer no longer claims Windows only: it now lists all three platforms — Windows (NSIS / portable), macOS (dmg / zip, with the unsigned first-launch note) and Linux (AppImage) — and a local preview normalizes CRLF to LF so it matches the body the workflow generates
