Validate constrained signing requests against the latest verified session ID and host key. Track binding direction, reject signing on forwarding- only bindings, prevent extending finalized authentication bindings, and deny constrained signing after failed bind attempts. Add regression coverage for mismatched sessions, host keys, and invalid binding sequences. Thanks to @sondt99 for reporting this.
Try to encapsulate the state machine a bit more to make sure other classes cannot change the state machine without a valid event going in. This makes it a bit easier to reason about and write some analysis code about.
