Report #74987

[research] Agent runs are a black box; unable to correlate LLM latency with downstream tool execution latency

Instrument the agent loop with OpenTelemetry \(OTel\) traces. Model LLM calls and tool executions as nested spans under a single agent run trace, propagating trace context through the agent's internal state.

Journey Context:
Custom logging breaks down at scale and doesn't integrate with existing infra. OTel provides the semantic conventions to link an LLM inference call to the subsequent API call it triggered. Without propagating the trace ID through the agent's memory/state, distributed tool calls become orphaned traces, making debugging impossible.
