fix: #64214
When autoClose is false, FileHandle.createReadStream registers a close listener on the handle. That listener is not removed after the stream finishes normally, so creating streams repeatedly on the same handle accumulates listeners.
In importFd, when autoClose is false, remove that listener and perform the corresponding unref cleanup when the stream ends (on end for read streams, on finish for write streams) or on error.
