ospab 8f0ffd08c0 feat(gui): TUN mode and autostart on Linux
Brings the Linux GUI up to parity with Windows. Four things blocked it, each
independently sufficient:

  - build.rs keyed the Windows-manifest step off cfg(windows), which in a build
    script describes the HOST. Cross-compiling the helper from Windows to Linux
    therefore took that branch and died with "Can only compile resource file
    when target_env is gnu or msvc". Now keyed off CARGO_CFG_TARGET_OS, with
    the cfg(windows) gate kept as a second check because winres is a host-
    resolved build-dependency and simply does not exist on a Linux host.
  - launch_as_admin was bail!("Windows only.") outside Windows. Implemented for
    Linux via pkexec, polkit's front-end, which raises a graphical auth prompt;
    sudo is unusable from a GUI with no terminal. Missing pkexec now names the
    package to install instead of failing opaquely.
  - The release workflow only built ostp-tun-helper in the Windows job, so the
    Linux package shipped without it. It is now built and placed next to the
    GUI binary, where find_helper_exe looks first.
  - set_autostart/get_autostart were no-ops off Windows. Implemented via XDG
    autostart (~/.config/autostart/ostp.desktop, honouring XDG_CONFIG_HOME),
    the direct equivalent of the HKCU Run key.

The helper's own code needed no changes — it already compiled for Linux once
the build script stopped rejecting it. list_running_processes already had a
Linux branch.

The token file is created 0600 on Linux: /tmp is world-readable there, unlike
the Windows temp dir, and that token authorises control of the privileged
helper.

Not verified on a live Linux desktop from here — the Tauri backend cannot be
compiled for Linux on a Windows host (GTK dev libraries), so the cfg(linux)
paths are reviewed rather than built. CI compiles them.
