crofty 0.12.0 — SFTP deploys no longer stall on the host-key prompt

A crofty deploy over SFTP froze at the prompt that asks you to trust a server’s host key the first time crofty sees it.

Before

crofty looked only at its own record of known servers (empty to start), so a server you’d reached over ssh/sftp many times was still treated as new and stopped to ask — freezing the deploy.

After

• crofty now reads your ~/.ssh/known_hosts (read-only). A server you already trust just deploys.
• For a genuinely new host, crofty deploy --yes accepts its key without the y/N prompt — for when an AI assistant is driving and no one’s at the keyboard (crofty agent lists --yes).

A host key that changes after it was first trusted is still a hard error.
