Teleport relay fallback is now scoped per attempt, with reconciliation if the standard path served a request the relay skipped

Claude Code has an internal relay for streaming requests, used when a session is being handed off between machines (teleportation). Previously, whenever this relay failed, it just fell back to the normal request path and logged that the relay stayed 'armed' (ready to try again). Now each failure is recorded with its reason, and the fallback request goes through the normal path as before. If that normal-path request succeeds while the relay still thinks it's active, Claude Code logs a warning that the normal path served a request the relay didn't take, and disarms the relay accordingly.
