Terra in base section; fix Hyprland via solopasha COPR

- Terra repo is added right after RPM Fusion in the base setup (it carries
  noctalia + mangowc). Modules keep calling add_terra_repo so they still
  work standalone; it is a no-op when terra-release is present.
- Hyprland was retired from the Fedora repos after F42 (dependency churn);
  the module could never resolve 'hyprland' on F44. It now enables the
  solopasha/hyprland COPR first — the de facto standard for F43/44 — and
  treats the accessory packages (hyprpaper/hyprlock/waybar/mako/wofi/
  xwayland-satellite) as optional so a name drift warns instead of aborting.
- README updated.
