v0.5.14 ships a working install but auto-install harness can't SSH-
validate post-reboot — admin user has no authorized_keys, hardened
sshd rejects all auth. SSH up + listening but no path to log in.
Fix: detect_seed_pubkey() searches /dev/sr* for a NoCloud cidata
volume (label "cidata"), parses ssh_authorized_keys: list from
user-data, returns first key. generate_ks() then embeds as
sshkey --username=admin "ssh-ed25519 AAAA... user@host"
right after the user= directive. Anaconda creates
/home/admin/.ssh/authorized_keys with right perms (700/600).
Real users: drop a NoCloud seed iso next to install media (or via
USB), pubkey lands automatically. auto-install.sh: existing run-vm.sh
seed logic already builds the cidata iso with host pubkey.
If no seed → directive line empty → anaconda treats as no-op → SSH
validation blocked but install otherwise unaffected.
