/**
 * Which span attributes carry conversation content, and in which direction.
 *
 * Two vocabularies land on the same spans: the ones eve sets on its own
 * `agent.*` spans, and the ones the AI SDK's OpenTelemetry integration sets on
 * the model-call spans beneath them. A destination that declined content has to
 * be rid of both, so both are listed here rather than in the module that writes
 * each.
 *
 * Listed by name rather than by prefix because the prefixes are shared with
 * metadata that must survive: `ai.response.finish_reason` and
 * `gen_ai.tool.name` say what happened, not what was said. The cost is that a
 * new content attribute in a dependency is not covered until it is added here.
