locally_managed_hosts() only scanned host-keys/ (now empty for all
current targets), so --remove and --regenerate-all-keys silently did
nothing. Fix:
- locally_managed_hosts(): also yields targets from
vars/per-machine/*/openssh/ssh_host_ed25519_key/secret, deduped
- cmd_remove: shows [clan-vars] or [host-keys/] label per entry;
deletes vars/per-machine/<target>/openssh/ in addition to host-keys/
- cmd_regenerate_all: same -- removes clan vars dirs before regenerating
Also update CLAUDE.md and README.md to reflect that all flake targets
now use clan vars (not just lxc-*); host-keys/ is only for the
auto-installer's own pre-seeding path.

Replaces the gitignored host-keys/ directory with clan vars as the
authoritative storage for SSH host keys. Keys are now generated as
sops-binary-encrypted clan var files (admin-key only) and checked into
vars/per-machine/<target>/openssh/, eliminating the plaintext private
key that previously had to live outside the repo.
Changes:
- modules/clan/ssh-host-key.nix: clan vars generator for the ed25519
SSH host key pair (neededFor="activation" — not mapped to sops.secrets,
delivered via tarball baking for LXC or --pre-format-files for VMs)
- flake.nix: add clanCore module + required settings to every mkTarget;
deduplicate bundled disko/sops-nix via follows; all 27 hosts eval clean
- flake.lock: updated to reflect the new follows constraints
- scripts/lib/clan-vars.sh: new helper library with
clan_ssh_key_exists / clan_ssh_pubkey_path / clan_decrypt_ssh_key /
clan_generate_ssh_key for use by the provisioning and sync scripts
- scripts/secrets/sync-host-keys.sh: queue_host_sync() now checks clan
vars first; generates via clan_generate_ssh_key if no key exists;
derives age fingerprint from clan pub key for .sops.yaml registration
- scripts/proxmox/create-proxmox-resource.sh: key management simplified
(sync-host-keys.sh now generates the key if missing, so the inline
prepare-host-key.sh call is gone); sync_remote_host_keys() decrypts
the clan key into a temp dir and scps just the two files to the node
when a clan key exists, falling back to the old host-keys/ scp for
any remaining legacy entries

New script: scripts/secrets/push-host-keys.sh
- Pushes newly-generated SSH host keys from host-keys/ to already-running
NixOS hosts after sync-host-keys.sh --regenerate-all-keys.
- Before pushing any key, checks that .sops.yaml and secrets/*.yaml are
committed and pushed to the remote Gitea flake (hosts rebuild from there,
so recipient changes must land first); offers to auto-commit/push if not.
- Reads /etc/flake-target from each host to confirm which key to install,
handling the case where multiple flake targets share a hostname.
- Deduplicates by hostname in --all mode; skips hand-registered targets
that have no host-keys/ entry.
- --dry-run, --skip-git-check, SSH_USER override (default: nixos).
sync-host-keys.sh --regenerate-all-keys:
- Updated pre-confirmation warning to distinguish already-running hosts
(need push-host-keys.sh) from not-yet-deployed hosts (need installer
image rebuild).
- Added next-steps block after regeneration completes pointing to
push-host-keys.sh --all.
recover-hosts.sh:
- Header and SSH host key mismatch warn now cross-reference
push-host-keys.sh as the proactive (pre-drift) alternative.

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.
