* Updated `AWSRequest` to use `data` instead of `buffer` in image upload logic

* Refactored `jsonrpc_handler` to use `Command` type and updated parameter handling

* Updated `StdioServer` to use binary streams for stdin/stdout and added subprocess-based test for framed JSON-RPC communication

* Fixed `StdioServer.write` to flush stdout buffer in a separate thread using `anyio.to_thread.run_sync`.

* Refactored `StdioServer` and `StdioClient` to pass and use captured `stdout` buffer, ensuring isolated binary protocol handling on `stdout`.

* Renamed `file_server.py` to `file_server_test.py` for clarity and consistency in test file naming.

* Removed explicit `stdout_buffer` handling in `StdioServer` and `StdioClient`, directly using `sys.stdout.buffer` for simplicity and consistency.
