@hackage shikumi-trace-otel0.1.1.1

An opt-in OpenTelemetry adapter for shikumi's hierarchical trace trees. Shikumi.Trace.OpenTelemetry.exportTree walks a finished TraceTree and emits one OTel span per node, preserving parent/child nesting (each child span is created in a context carrying its parent span). LM-call spans carry GenAI semantic-convention attributes; every span carries shikumi.-prefixed span-kindcostlatency/retry attributes. The heavy hs-opentelemetry-* dependency tree is isolated in this package, mirroring baikai's baikai-trace-otel split.
