qianze c22f11de38 fix(stream): prevent non-JSON SSE lines and duplicate [DONE] from breaking clients ...

- Passthrough: skip non-JSON data lines instead of forwarding raw garbage
- Translate: stop emitting redundant [DONE] sentinel (message_stop terminates)
- Add streamDoneSent flag to prevent duplicate [DONE] across transform + flush
- Warn on unexpected upstream Content-Type for streaming responses
