SseLineDecoder class final

Transforms a stream of byte chunks into a stream of lines.

Handles all three SSE line delimiters: \r\n, \r, and \n, including delimiters split across chunk boundaries.

Lines exceeding maxLineLength bytes are discarded and a StateError is added to the output stream.

Used only by the dart:io transport — the web transport relies on the browser's native EventSource which handles line splitting.
