- customize_airootfs.sh stages dots-hyprland at /opt, runs ./setup
install-deps as a throwaway builder, harvests the built packages into
/opt/localrepo so pacstrap resolves them offline
- image ships its own [local-aur] (file:///opt/localrepo); CI and
localrepo/update.sh keep that copy in sync; .gitignore covers work/,
out/ and airootfs/opt/localrepo/
- alvin-install runs ./setup install --skip-alldeps on the target
- clone pctrade/end4-pC into /etc/skel/.config/quickshell, patch qsConfig
ii -> end4-pC in the staged variables.lua (guarded + idempotent), and
restore the fork after setup rsync --delete's ~/.config/quickshell
- ship user presets in skel, point fish `q` alias at end4-pC
- AGENTS.md: document the fourth package source and new gotchas
