gsxdsm 5b9ff047d3 FN-6599: preserve chat thread during streaming attach ...

Keep existing chat history visible when attaching to an in-flight streaming response.

- Commit attach-triggered message loads for the streaming session before active session refs settle.
- Avoid clearing cached main chat messages on attach cache misses while fetching prior thread history.
- Add regression coverage for main chat and QuickChat streaming thread visibility, plus quarantine ledger updates.
