chore: 停发并归档 Electron 桌面版,产品只保留便携 U 盘版

桌面 Electron 版是商业版 ClawX 已做得更好的事的劣化版,且启动坑多
(冷启动建编译缓存 >30s 撞写死的 30s 硬超时,绿色版每次解压 837MB
永远冷启动)。U-Claw 的本质是「插上 U 盘解压即用」,故停发桌面版,
只发便携版。

- release.yml: 删除 desktop-windows / desktop-mac 两个 job;publish
  只依赖 portable-windows-full;发布说明去掉桌面安装版/dmg,只留便携版
- u-claw-app/DEPRECATED.md: 新增归档说明(停发原因、坑、如何捡回)
- u-claw-app/src/main.js: 顺带修 gateway 超时 30s→180s + spawn 加固定
  NODE_COMPILE_CACHE(让归档代码处于可用状态)
- 删除 usb-release/: portable/ 的老前身,2026-04 后无人维护、全仓库零
  引用,是「为什么有两个 U 盘版」的混乱源
- README.md / CLAUDE.md: 分发形态更新为便携版唯一主发
