Subject: [PATCH] feat(hyprland): enable native Wayland for Electron apps

Set NIXOS_OZONE_WL in the compositor env so Chromium and Electron
wrappers select native Wayland rather than XWayland, which blurs at this
DPI. Deliver it through Hyprland's env directive because UWSM starts the
session without the shell profile home-manager's sessionVariables rely
on.
