feat: Cagebreak greeter path + Hyprland deprecation (draft)#78
Merged
Conversation
Add cage as the recommended greetd backend (lite mode: Kitty-only, no gSlapper wallpapers at startup). Hyprland greeter support remains functional but is marked deprecated with ~3 month removal timeline. Includes design spec, implementation plan, installer/Nix/postinstall integration, docs, launcher script, and verify script. Addresses #69.

Summary
Implements #69: add Cagebreak as a greeter backend and begin phasing out Hyprland for the greeter session. Cagebreak replaces Hyprland; niri remains the default compositor.
Pivoted from the earlier Cage Lite draft: Cagebreak supports wlr-layer-shell, so gSlapper wallpapers (secondary monitors) work as they do under niri and sway. Hyprland is not removed in this PR — it stays functional, marked deprecated with a ~3 month removal timeline.
Architecture
No Go changes to sysc-greet itself.
