Summary

add ~/.xprofile so Arch LightDM loads the standalone Home Manager session environment before Qtile starts
prepend the Home Manager profile to XDG_DATA_DIRS so j4-dmenu-desktop discovers Home Manager .desktop files
import the graphical session environment into the user systemd manager
revert the NixOS-only Qtile startup change from #81 because this workstation is using Arch LightDM

Root cause

Arch LightDM starts Qtile through /etc/lightdm/Xsession, not ~/.xinitrc. The wrapper sources ~/.xprofile, so the Home Manager environment needs to be established there. Without the Home Manager profile in XDG_DATA_DIRS, applications such as Brave remain installed but are invisible to j4-dmenu-desktop.

Deployment

The repository uses GNU Stow, so after pulling the merge, stow . will link .xprofile into the home directory. A new LightDM login is required for the session environment to be rebuilt.
