Turn the agent-install playbook into a full provisioning + maintenance
path. Solves the bootstrap chicken-and-egg: first contact uses an
operator-supplied password (one run, never stored), which creates a
dedicated `steward` login account with NOPASSWD sudo + Steward's managed
public key. Every run thereafter connects as `steward` with the managed
key — fully unattended (scheduled prune, agent updates).
- core/crypto: generate_ssh_keypair() — ed25519, OpenSSH formats.
- settings: ansible.ssh_public_key (non-secret, displayed) + ansible.ssh_user
(default steward); to_ansible_cfg extended.
- settings UI + route: "Generate managed key" (private encrypted, public
shown to copy) + SSH-user field.
- executor: build_bootstrap() writes a 0600 vars file (-e @file) for the
per-run user/password — never argv, never DB, never logged; drops the
managed key when a bootstrap password is given; --user floor from the
global ssh_user when no override.
- runner.trigger_run: pass-through `connection` kwarg, deliberately NOT
persisted on AnsibleRun.params (password stays out of the DB).
- bundled/host_agent/provision.yml: create steward user + authorized_keys
+ /etc/sudoers.d/steward (visudo-validated) + agent install.
- host_agent: /provision route + "Provision a fresh host" card (bootstrap
user/password; injects pubkey + user + token as space-safe JSON hostvars).
- Dockerfile: add sshpass (Ansible shells out to it for password SSH).
- tests: keypair generation + build_bootstrap (secret stays off argv).
