## Why Newline-delimited stdio input could buffer an unterminated JSON-RPC message without a per-message limit. Apply the same 64 MiB ceiling used by the other exec-server transports. ## What changed - Read stdio messages with bounded lookahead and disconnect when a message exceeds the limit. - Preserve LF and CRLF framing, including messages whose payload is exactly at the limit. ## Testing Added tests for accepting a limit-sized CRLF message and rejecting an unterminated overlong message.
