alvinlollo 8501a60165 fix(installer): chown target files by numeric id, not live-medium name
The end-4 step's chowns ran on the live medium, whose /etc/passwd has
no $USERNAME (the user exists only inside /mnt), so 'chown -R
alvin:alvin' failed with "invalid user" and the ERR trap aborted the
install at line 543. Resolve uid/gid once via arch-chroot id and chown
by number; the three remaining name-based chowns (fork/fish/hypr
restores) would have hit the same wall later.

Replace those three mid-function chowns with one catch-all over the
target home after the last root-side write: sed -i on the presets
rewrites through a temp file, which leaves them root-owned with no
chown after it.

systemctl --user enable ydotool.service could never work inside the
chroot (no /run/user/UID/bus exists before boot; it only ever warned
with "Failed to connect to user scope bus", so ydotool never
autostarted). Write the symlink enable would write:
~/.config/systemd/user/default.target.wants/ydotool.service ->
/usr/lib/systemd/user/ydotool.service.
