3.8.6
(fix): Fixed SSE stream terminator parsing for OpenAI-style data: [DONE] format. Terminators are now
checked after data extraction and only at event boundaries to prevent data loss.
3.8.5
(fix): Fix SSE parser concatenating multiple events into malformed JSON. Events are now properly
separated at blank line boundaries per SSE specification, with correct handling of multiline
data fields and stream terminators.
