Rename published packages and installers from maturita-* to graduately-*.

Keep temporary legacy aliases on the builds branch so older updaters still find downloads.

+# Carries no application of its own. Fastly caches branch-named URLs on
+# raw.githubusercontent.com, so this script looks up the tip of `builds`
+# and downloads that commit — not a stale AppImage from the last five minutes.
+#
+# Double-click the file (or run: sh graduately-installer-linux.sh).
+# The app updates itself from then on.
