The panel now lets the deployer decide which release keys it trusts. The
official CI key is built in and always trusted; an own P-256 public key can be
added (off by default, the private key is rejected) so manifests signed with it
are accepted too. Removing it drops the manifests only it signed. Changes are
audited and need update.confirm.
Admin UI: System > Trust > "Trusted release keys" with a collapsible guide on
generating a key pair and signing a manifest with openssl.
Registration now has one path, POST /api/release/offer (no token, signature
verified). The admin POST /releases route, the release.publish capability and
the ci-release preset are removed.
Join codes need no passkey touch and carry only public values (genesis
fingerprint, owner credentials, installer hashes). Nodes pin the genesis and
owners at enrollment and only follow passkey-signed operator set versions.
The panel's server key is listed in the set; pinned nodes require its
signature and run the control link under AES-256-GCM. Password sessions carry
no capabilities. The updater adopts a next_key from a signed manifest.
Bump version to 0.2.0. [CI SKIP]
