feat(launcher): SimpleLite 进程独立化与 DLL 热更新

- FollowParent=false 时在 Windows 用 cmd /c start 脱离父进程组，关闭 MiGu.Server 不再连带结束 SimpleLite - 新增 SimpleLiteBuildSync：SimpleLite 未运行时把 obj/Debug 最新 DLL 同步到 bin/Debug，并探测「前往站点」API 是否可用 - 新增 RestartForUpdate 与 POST /api/health/simplelite/restart-for-update：一键关闭、同步、重启以加载新 API - 诊断增加 FollowParent / GotoSiteApiAvailable / DeployHint；新增 scripts/redeploy-simplelite.ps1 部署脚本 - Dispose 增加 _disposed 幂等保护，避免重复释放
