feat: The script is now steamify.sh

- setup-gamescope-boot.sh renamed to steamify.sh; all references updated.
- Releases publish the bundle as steamify.sh and, for older install commands, setup-gamescope-boot.sh.
- The Steamify shortcut runs steamify.sh.

+# steamify.sh - Steamify CachyOS
+#
+# Wizard that makes a CachyOS (KDE Plasma) install behave like SteamOS:
+# boot into a Steam Deck-style gamescope session, switch to the Plasma
+# desktop and back, and reset to gamescope on the next boot/logout.
+#
+# It opens with a menu that detects which components are on and turns
+# them on or off to match what the user picks; turning one off restores
+# what was there before (system files from .bak-gamescope-wizard backups,
+# KDE settings from the undo journal in lib/state.sh). Components live in
+# lib/, see README.md. Safe to re-run.
