Subject: [PATCH] gentoo install scripts: guard with os_family like overlays
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both run_once_20-install-user-packages-gentoo.sh.tmpl and
run_once_40-install-sway-gentoo.sh.tmpl were missing the os_family
template guard (the overlays script got it in the previous fix but
these two slipped through). On non-gentoo boxes — arch, debian —
chezmoi apply would run them and they'd try to 'emerge', failing
with 'sudo: emerge: command not found' and exit status 1, which
breaks topgrade.

Wrap each body in '$0{ if eq .os_family "gentoo" }' / '$0{ else }',
mirroring the chaotic-aur script's pattern and the overlays fix from
the previous commit. On non-gentoo boxes the rendered script reduces
to a single 'skipping' log line and exits 0; on gentoo boxes the full
body (including the existing .sway_setup gate on the sway script) is
preserved.

Verified by rendering both scripts with a gentoo-config override:
  arch (live)  -> 'skipping gentoo user-packages' / 'skipping sway'
  gentoo        -> full body (293 / 87 lines)
Both pass bash -n and actually exit 0 when run on this arch box.
