Upgrading systemd runs its post_upgrade scriptlet mid-transaction, which
reexecs both the system manager and every user manager. When pacman runs
inside a user-session scope (the floating update terminal), that reexec
can SIGKILL it and abandon the transaction halfway, with packages
upgraded but none of the post-transaction hooks run.
Route every Omarchy-owned system mutation through a new hidden
omarchy-update-pacman helper that registers the transaction as a PID 1
scope via systemd-run, keeping it out of the user manager's cgroups.
System scopes survive the system manager's own reexec, and as a bonus the
transaction now also survives its terminal window closing. On unbooted
systems (the installer chroot) the helper runs pacman directly.

Fires after the channel template is copied to /etc/pacman.conf and before
`pacman -Syyuu` runs, letting users layer custom Pacman repositories or
IgnorePkg directives onto the freshly-written config so they're respected
by the upgrade. Useful for users running on overlay distros (CachyOS,
Chaotic-AUR, internal company repos) where a wipe-and-reinstall would
otherwise pull vanilla Arch versions.
Ships with `pre-refresh-pacman.d/add-custom-repo.sample` showing the
pattern.
