Installer/installation flow led to system-wide breakage after enabling Millennium via / etc/ld.so.preload on Arch Linux

Bug

After running the Linux install flow, my Arch/CachyOS system became corrupted.

The most suspicious command was:

sudo pacman -U --noconfirm ~/.cache/paru/clone/millennium/millennium-3.0.0_beta.17-1-
x86_64.pkg.tar.zst && sudo sh -c 'echo "/usr/lib/millennium/
libmillennium_bootstrap_86x.so" > /etc/ld.so.preload'

## Result

Critical system files ended up owned by nobody:nobody instead of root:root, including:

- /etc
- /etc/sudo.conf
- /etc/sudoers
- /usr/bin/sudo
- /usr/bin/su
- /usr/bin/passwd
- /usr/bin/pkexec

sudo now fails with:

sudo: /etc/sudo.conf is owned by uid 65534, should be 0

## Notes

I checked the temporary helper scripts and did not see obvious chown calls there, but
the install flow that writes Millennium into /etc/ld.so.preload looks very dangerous
and may be related.

## Expected

The installer should never risk system-wide breakage or modify anything in a way that
can affect the whole OS outside Steam.
