bastien 872079bafb feat(install): offer /tmp on disk + SSH memory guard, deploy cloudpex helper

/tmp is a RAM-backed tmpfs on Ubuntu (50% of RAM). Agent runs fill it: half
the RAM goes, then every temp-file creation fails with ENOSPC and shells
break. Swap does not lift the cap, so the fix is /tmp on disk.

End-of-install offers (Linux, [y/N], skipped without a terminal, idempotent):
- offer_tmp_on_disk: mask tmp.mount + etc/tmpfiles.d/tmp.conf (wipe at
  boot, 10-day purge, /var/tmp rule kept). Effective at next reboot.
- offer_ssh_memory_guard: the previous server's rules. ssh.service drop-in
  (OOMScoreAdjust=-1000, MemoryMin=256M) + earlyoom with --avoid sshd and
  --prefer node/java. MemoryMin covers sshd only; earlyoom is the real guard.

install_cloudpex deploys the NAS mount helper in the Linux block.
Docs: README steps 12-14 + table, CLAUDE.md layout + lint command.

 # /tmp on disk (install.sh masks tmp.mount): keep the tmpfs semantics — wipe /tmp
 # at boot (D) and purge entries untouched for 10 days. Same file name as
 # /usr/lib/tmpfiles.d/tmp.conf, so this REPLACES it: the /var/tmp rule must stay.
