The script was root-only and hard-coded /etc/nix/nix.conf and
/etc/ssh/ssh_known_hosts, making it always fail (non-fatally) when
called as a non-root SSH user from create-proxmox-resource.sh.
Add dual-mode detection based on EUID:
- root (multi-user/daemon): existing behavior unchanged -- writes
/etc/nix/nix.conf, /etc/ssh/ssh_known_hosts, restarts nix-daemon
- non-root (single-user): writes ~/.config/nix/nix.conf and
~/.ssh/known_hosts, creates the config file if missing, skips the
daemon restart (single-user has no daemon), defaults REMOTE_BUILDER_KEY
to ~/.ssh/id_ed25519 instead of /root/.ssh/id_ed25519
create-proxmox-resource.sh already calls the script without sudo (as the
SSH user), so no change is needed there -- the script now handles both
cases on its own.

variables.nix's nixCacheHostKey no longer matched nix-cache's actual SSH
host key (confirmed via ssh-keyscan against the live container), so every
declaratively-configured client's programs.ssh.knownHosts trusted the
wrong key -- distributed builds would fail host-key verification. Also,
modules/nix-cache/remote-builder-client.nix hardcoded sshKey to
/root/.ssh/nixremote, but the `server` host only has its own default
/root/.ssh/id_ed25519 installed (confirmed live via qm guest-agent) --
that file was never even present, so the build machine config pointed at
nothing. Standardize on each client's own default identity, matching the
per-host-key pattern vars.remoteBuilderAuthorizedKeys already uses instead
of a shared/differently-named keypair, and add
scripts/secrets/sync-nix-cache-host-key.sh (wired into
codex-maintenance.sh's --check) so the host-key drift doesn't silently
recur next time nix-cache is rebuilt or recreated.

scripts/ had grown to 10 top-level scripts covering three distinct
concerns (sops/age + SSH host-key management, Proxmox deployment, and
repo-wide bootstrap/CI) with no grouping. Move the key-management scripts
(backup-admin-key.sh, rotate-admin-key.sh, prepare-host-key.sh,
sync-host-keys.sh) into scripts/secrets/, and the Proxmox scripts
(create-proxmox-resource.sh, configure-nix-cache-client.sh) into
scripts/proxmox/; leave env.sh, codex-setup.sh, codex-maintenance.sh, and
bump-nixpkgs-release.sh at the top level (frequently hand-typed or pure
shared config) and scripts/lib/ as-is.
Updates every cross-reference: each moved script's repo_root computation
(now one directory deeper), shellcheck source= directives, inter-script
paths (create-proxmox-resource.sh's call into sync-host-keys.sh and its
remote bootstrap of configure-nix-cache-client.sh on the Proxmox node),
and every doc/module mention (CLAUDE.md's Scripts section reorganized to
match, README.md, docs/auto-installer.md, docs/proxmox-images.md,
modules/installer/common.nix, modules/platforms/lxc.nix). CI workflows
need no change -- they only invoke codex-maintenance.sh, which didn't
move. Verified via bash -n, shellcheck (no new warnings beyond the
pre-existing SC1091/SC2029/SC2095 baseline), and live dry-runs of
sync-host-keys.sh --all and create-proxmox-resource.sh --list from their
new paths.
