zhaowei.huangandCursor 42978930ca feat: 迁入 MiGu.Server、平台前端与车辆列表 reflection 回退
从 Simple-FR 拆出 Platform.Server 并重命名为 MiGu.Server;frontends 源码与构建脚本迁入本仓库。地图监控在 projection/cars 失败或为空时回退 reflection 车辆列表;Simple 仓库已移除旧 Platform.Server。

// S2 根治 (会话45):让 MiGu.Server 启动时自动优先把 frontends/apps/simple-platform-vue/dist/
// 作为 WebRoot —— 解决「每次 vite build → wwwroot/index.html 都被 hash 漂移 → 提一个噪音 commit」
// 的死循环。
//
// 探测策略:从 ContentRootPath 出发向上逐级找 frontends/apps/simple-platform-vue/dist/index.html,
// 找到则将 WebRootPath 改指到 dist;找不到则保持默认 wwwroot/(用于「克隆后没跑 build」或
// 生产部署机不带 node 的场景,wwwroot/ 由 build-platform-frontend.bat 的 robocopy /MIR 兜底)。
//
// 影响:
// - dev 模式:跑过一次 `pnpm build` 后无需 robocopy,重启 MiGu.Server 即生效;
// 也不再需要 commit wwwroot/index.html。
// - 部署:CI/CD 走 build-platform-frontend.bat 把 dist 同步到 wwwroot/dist 此时不存在
// 于发布产物中 → 自动 fallback 到 wwwroot/。行为与改造前一致。
