Under the hood
Remote session forwarding now classifies outcomes directly instead of using an HTTP DELETE.
Remote session forwarding no longer closes a session by sending an HTTP DELETE. Instead, forwarding outcomes are now classified directly: sent, unchanged, and conflict_resolved map to success, while outcomes like raced, lane_full, unauthorized, deadline, failed, and aborted map to failure. This is part of a reworked remote command-forwarding/session-sync path.
