NixOS copies mode-carrying /etc entries such as authorized_keys.d during
stage-2 activation, which runs before systemd starts. preservation mounted the
persisted /etc/ssh from preservation.target afterwards and hid that copy, so a
key change only took effect on `switch`: revoking a key and rebooting silently
restored the old one.
Prepare the mount in initrd, before activation runs, and cover it with a VM
test that seeds a stale authorized_keys file, reboots, and asserts the declared
key replaced it. The same test fails on that assertion with inInitrd disabled.
Verified on all four hosts: /persistent/etc/ssh/authorized_keys.d/root is now
rewritten at boot instead of keeping the timestamp of the last switch.

* chore(nix): update nixpkgs to e62746b and fix 26.11 breakage
Bump nixpkgs to e62746b and preservation to 00be7f7, then adapt to the removals and renamed options in the new revision: drop the removed boot.initrd.systemd.enable settings, trim the stale emSign CA blacklist on Linux while keeping it for the older Darwin input, and migrate Avahi publishing to settings.publish. Work around sunshine still setting the legacy Avahi options and keep dsh-nu on its tested Nushell 0.115.1. Patch NUR dsh's pnpm call to pass nodejs = null, and update pyclipsync for the stdenv.hostPlatform.system rename.
* chore(nix): refresh flake inputs for 26.11
- update nixpkgs-darwin to the same e62746b revision as nixpkgs
- make dsh-nu follow main nixpkgs and patch its testedWith manifest for the resolved Nushell
- refresh floating inputs; update lanzaboote, tuios, and ponytail
- drop the nixpkgs-2505 and rust-overlay workarounds
- keep pyclipsync on main and simplify the cross-platform CA blacklist
- adopt home-manager's Nushell loadSessionVariables default
* fix(gitea): use ROOT_URL for nixpkgs 26.11
nixpkgs removed the legacy settings.server.DOMAIN option; the existing ROOT_URL already carries the public URL.
* chore(nix): update dsh-nu to 0.7.0

On a tmpfs root the flake/fetch cache is empty at every boot, so
`nix run <flake-ref>` re-downloads its input and fails until DNS is up: a reboot
test showed llama-swap's first start failing on that. Other caches write into
RAM meanwhile.

The Z890 board and its root SSD move here from `ai`, and the retired VM's name and 192.168.5.101 are reused.
