- WorkspaceHelper: Zentrale Hilfsmethoden (IsWindows, TempDir, IsSubPathOf, GetRelativePath, ShellExecutable, ShellArguments) - ToolService: execute nutzt cmd.exe auf Windows, GetRelativePath mit Forward-Slashes, IsSubPathOf für case-insensitive Pfadprüfung - SessionEndpoint: /tmp → Path.GetTempPath(), bash → cmd.exe, Fire-and-forget via .bat statt systemd-run auf Windows - ChatService: /tmp → WorkspaceHelper.TempDir - MemoryService: IsSubPathOf + GetRelativePath - WorkspaceEndpoint: HandleBrowse zeigt Laufwerke auf Windows, IsSubPathOf statt StartsWith - InfoEndpoint: gott.exe auf Windows, isWindows-Flag in API-Response - Frontend: File-Explorer mit Laufwerks-Navigation auf Windows
