- post-install: ensure the `microcode` initramfs hook (after autodetect) so
installed systems carry CPU ucode — the live ISO embeds it, so nothing is
staged onto the target otherwise. Rebuild all presets with `mkinitcpio -P`.
- post-install: drop the nonexistent `sd-plymouth` hook branch; only the udev
`plymouth` hook exists. Set the theme then rebuild once.
- packages: add zathura + zathura-pdf-mupdf (BOS had no PDF viewer) and
libva-utils (`vainfo`); the Mesa VA-API backend now ships in `mesa` itself.
- bos-welcome: on first run, if NetworkManager isn't fully online, open nmtui
so the user connects before the first bos-update/pacman (avoids confusing DNS
errors on a fresh install). Float the bos-netsetup window like bos-welcome.
