[research] Implementing effective tracing for complex, multi-step agent loops

Instrument agent loops using OpenTelemetry \(OTel\) with specific semantic conventions for GenAI. Create a trace for the overall task, spans for each LLM call, and nested spans for tool executions. Propagate trace IDs across agent handoffs.

Journey Context:
Simply logging prompts and responses is insufficient for agents because the causal chain is dynamic. Developers often rely on print statements or basic logging, which fails when an agent loops or hands off to another agent. By adopting OTel and traces/spans, you get a directed acyclic graph \(DAG\) of the agent's execution. This allows you to measure latency per tool, token consumption per step, and pinpoint exactly where a loop started or a handoff failed.
