SSH-key-domain natives. Wraps server::command::{ListSshKeys, RemoveSshKey, UserHasSshKey, LookupUserBySshKey}. AddSshKey is deliberately NOT
exposed: pubkey upload stays on the dedicated ssh-copy-id exec flow so the
eval channel can never be used to register impersonation keys.
v1 binds list-ssh-keys for the authenticated session user. The other
three (remove / user-has / lookup) take string arguments and ride the
follow-up slice that lands the host-side StringRef-arg plumbing.
