fix(tui): stop streaming markdown/code after message completes

[mocksoul]

Summary

• TextPart passes streaming={true} unconditionally — even for completed messages
• This causes opentui to always skip the last table row (treated as potentially incomplete)
• Derive streaming state from message.time.completed so finished messages render all rows

Fixes#13855

Note

Full fix requires companion change in opentui (streaming setter must rebuild tables on true→false transition). See anomalyco/opentui#696

  • fix(tui): stop truncating last table row after streaming completes #13674

Why related: This PR addresses the same issue — preventing the last table row from being truncated/skipped after streaming completes. Both PRs are fixing the same behavior where incomplete messages cause the last row to be dropped, and both likely involve adjusting the streaming state logic for completed messages.

Thanks for working on this fix! I was also investigating the same issue (Bug #13855) and started implementing the same solution with createMemo(() => !props.message.time.completed). Great to see you already have a PR for this!

Looking forward to this being merged! 👍
