[research] Long-running agent tasks timeout or fail without leaving a trace, making debugging impossible

Implement streaming telemetry and checkpointing. Emit OpenTelemetry spans for every tool execution and LLM call, and save agent state to persistent storage at each step.

Journey Context:
Agents can run for minutes or hours. If the process crashes, all context is lost. Standard logging is insufficient for complex agent graphs; structured tracing allows you to reconstruct the exact state and tool outputs at the point of failure without re-running the entire pipeline.
