[research] Standard logging obscures agent decision loops and tool call latency, making it impossible to isolate bottlenecks

Implement OpenTelemetry \(OTel\) tracing with distinct spans for: LLM inference, tool execution, and agent reasoning loops. Attach the prompt token count and tool payload as span attributes.

Journey Context:
Print statements or basic logs flatten the execution trace. When an agent takes 30 seconds, you can't tell if it was the LLM thinking, a slow API call, or a loop. OTel spans provide a hierarchical view \(Trace -> Agent Span -> Tool Span\) with timing, allowing you to pinpoint exactly where latency is introduced and if retries are occurring.
