refactor(fws-keys): make keyboard shortcuts tool universal for hyprland and i3

Rename fws-hypr-keys to fws-keys and extend it to support both Hyprland and i3 desktop environments. The tool now detects the session type and uses appropriate methods:

- Hyprland: queries hyprctl binds for real loaded bindings (wofi dmenu)
- i3: parses ~/.config/i3/config with variable resolution (rofi dmenu)

Update all references in configs and templates. Add VM detection warning in fws-vr-setup to prevent VR attempts in virtual machines where GPU/USB access is unavailable.

Add ttf-liberation font dependency for Steam UI stability on minimal installations and improve error guidance for Steam crashes.
