The old Recommends named python3-pyside6 (no such package on Debian/Ubuntu —
PySide6 is split per module), so apt skipped it and the GUI couldn't start.
Now Recommends the real modules (python3-pyside6.qt{widgets,gui,websockets,svg}
+ python3-pyte) AND the optional diagnostic/gaming tools (smartmontools,
lm-sensors, dmidecode, pciutils, libnotify-bin, libsecret-tools, gamemode,
mangohud), so 'apt install rigdoctor' sets up the whole toolset automatically —
no manual installs. cpupower -> Suggests. Verified all candidates resolve in apt.
