CI package check failed on main (400/402):
- syncthingtray-qt6 no longer exists in the AUR (RPC returns nothing);
the qt6 build is now the official 'syncthingtray' package in extra/
cachyos - rename it in packages.x86_64 and drop the dead
AUR_MISSING entry from build-end4-deps.sh
- neofetch left the distro repos (only chaotic-neofetch-git remains);
build the AUR package locally (7.1.0-2, PGP-verified against Dylan
Araps' key) and commit it to localrepo/ with a reindexed local-aur
db so both the CI check (file glob) and pacstrap ([local-aur]) work
- un-indent the package lists in build-end4-deps.sh: CI accepts
repo-less packages via 'grep -qxF <name>' (exact whole-line match),
which could never match indented names
Verified locally with an exact replica of the CI check: 402/402.
