Update README.md

Adds build, install, and uninstall targets with standard PREFIX/DESTDIR
support. Installs binary, desktop file, metainfo, GSettings schema,
app icons, scalable action icons (outlay + tabler), and bundled fonts.
This allows distro packagers (Nix, Arch, Debian, etc.) to properly
install icons alongside the binary so GTK can find them at runtime.
