- Store chat turn context (chatId, turn, continuation, clientData) in locals for auto-detection
- toolFromTask now auto-detects chat context and passes it to subtask metadata
- Skip serializing messages array (can be large, rarely needed by subtasks)
- Tag subtask runs with toolCallId for dashboard visibility
- Add ai.toolCallId() convenience helper
- Add ai.chatContext<typeof myChat>() with typed clientData inference
- Add ai.chatContextOrThrow<typeof myChat>() that throws if not in a chat context
- Update deepResearch example to use ai.chatContextOrThrow
- Document all helpers in ai-chat guide
