AsyncRequestNotUsableException is thrown when the SSE client disconnects before the server finishes writing (normal: browser tab close, MCP client reconnect). The catch-all handler was logging it at ERROR level and then attempting to write a JSON ErrorResponse onto a text/event-stream response that no longer had a converter, producing a second spurious HttpMessageNotWritableException log entry. Fix: add a dedicated @ExceptionHandler(AsyncRequestNotUsableException) that logs at DEBUG only and returns void (no body).
