Introduces the 'file_retention' field with a value of 30,000 to the upload test payload in OneBotUploadTester. This may be used to specify file retention duration in milliseconds.
Introduces a 'file_retention' parameter to control how long uploaded files are retained before automatic deletion. If set, files are deleted after the specified duration; otherwise, they are not automatically removed. This helps manage temporary file storage and cleanup.
Introduces new OneBot actions for streaming file upload and download, including chunked file transfer with memory/disk management and SHA256 verification. Adds CleanStreamTempFile, DownloadFileStream, UploadFileStream, and TestStreamDownload actions, updates action routing and network adapters to support streaming via HTTP and WebSocket, and provides Python test scripts for concurrent upload testing.
