ptyd was migrated to the SchemeDaemon/ready_with_fd path: it registers the
"pty" scheme and signals readiness by sending its scheme cap fd back to
init, which init receives via call_ro(FD) in its scheme-service startup.
The service was still declared type="notify", so init waited for a plain
readiness byte ptyd never sends and blocked forever at ptyd — before the
console/login stack could start (post-switchroot boot hang). Declare the
correct type={scheme="pty"} so init uses the matching fd-receive path.
