Key changes:
- lib/distro.sh: replace REPO_ADD_RPM variable with repo_add_rpm()
function (DNF5 changed 'config-manager --add-repo' to
'config-manager addrepo --from-repofile=')
- 01-repos.sh: use repo_add_rpm function; add Ghostty COPR for
Fedora; remove Signal RPM repo (no official one — use Flatpak)
- 02-packages.sh: lowercase 'development-tools' group for DNF5;
add python3-devel (needed for native extensions like evdev);
swap ffmpeg-free → ffmpeg via RPM Fusion for full codec support;
use tuned (preinstalled on Fedora) instead of TLP
- 11-tweaks.sh: conditional power management — TLP on Debian,
tuned on Fedora
