verify: whether Anypoint Monitoring or Agent Visualizer ingests OTLP GenAI spans #257

What needs verifying

Whether the platform ingests OTLP GenAI traces, and in what format.

Why it matters

Build guide 1.6 is explicit: do not promise "shows up in Agent Visualizer"
until someone internal confirms it. Ship "exports OTLP" and let the sink be the
customer's choice. If the answer is yes, it becomes a headline feature — but it
must not be claimed before then.

Done when

• A confirmed yes/no, with the accepted format if yes.
• Docs updated to state the answer plainly either way.
