Set CLI child working directory to the workspace

The Claude CLI child process inherited the gott server's CWD because
CreateCliStartInfo never set WorkingDirectory. On Linux systemd usually
sets WorkingDirectory= to the workspace, so it worked by accident; on
Windows the service starts from its install directory, so the CLI's own
built-in tools resolved relative patterns (e.g. Glob "Sources/**")
against the wrong directory and returned "No files found", while
absolute paths still worked. --add-dir only grants access, it does not
set the CWD.

Thread the workspace through ChatStreamingAsync -> RunCliStreamingAsync
-> CreateCliStartInfo and set psi.WorkingDirectory (guarded by
Directory.Exists). GetStatusAsync stays without a CWD.
