Initial commit: Hyprland 0.57 rice for Fedora 44

Dark minimalist setup for a sysadmin workstation: rounded blur windows with
the DMS pink accent, keyboard-driven SSH hub (Mod+S), run-or-raise app
binds, Alt+Tab window switching, OCR of screen regions, hotkey cheatsheet,
DMS network-editor plugin and the systemd session target for portals.
