Enables SSH certificate and WebAuthn/FIDO2 passkey authentication
for both terminal and SFTP connections, including UI for key and
certificate selection and passphrase entry. Updates agent and SSH
bridge logic to handle certificate, passkey, and fallback methods,
and patches signature algorithm handling for certificate auth to
ensure correct signature formats and algorithm negotiation.
Improves compatibility with modern SSH deployments and enhances
security by supporting hardware-backed and certificate-based keys.
