The core, hyprlua and hyprland package installs used backslash-continued
`pacman` commands with inline `#` comments. Bash treats the first inline
comment as the end of the command, so pacman ran with only the packages
before it and every later name (7zip, cronie, nwg-dock-hyprland, …) was
executed as a shell command — failing under `set -e`. Move all three lists
into arrays, where per-item comments are valid, and install with `--`.
Also:
- himalaya: install the official `himalaya` package (AUR `himalaya-bin` is gone).
- mail-notmuch / caldav-sync: make the systemd *user* timer setup and the
initial sync best-effort. A bare TTY/chroot install has no user session bus
(and ~/.config may not be writable yet), so `systemctl --user` and the mkdir
could abort the module; warn and continue instead.
