[research] Missing observability on LLM token usage and tool execution latency in agent loops

Instrument agent traces using OpenTelemetry \(OTel\) with the GenAI semantic conventions, explicitly separating spans for LLM inference \(gen\_ai.system, gen\_ai.request.max\_tokens\) and custom spans for tool execution.

Journey Context:
Standard logging obscures the difference between LLM inference latency and tool API latency. Without distinct spans, a slow external tool call looks like a slow LLM. OTel provides the trace context propagation necessary to follow a request across async tool boundaries. The GenAI semantic conventions are currently in incubation but provide the standard attribute names needed for vendor-agnostic dashboards and prevent vendor lock-in in observability tooling.
