genkit_otel 0.1.0

OpenTelemetry GenAI semantic-conventions instrumentation for Genkit Dart (traces, metrics, and message-content capture).

0.1.0

• Initial release: GenAiInstrumentation, an OpenTelemetry GenAI semantic-conventions provider for Genkit built on dartastic_opentelemetry.
• Emits gen_ai.* client spans for model operations, optional execute_tool spans, and generic spans for other Genkit action types.
• Emits the GenAI client metrics gen_ai.client.token.usage and gen_ai.client.operation.duration.
• Optional message-content capture via contentCapturingMode (noContent/spanOnly/eventOnly/spanAndEvent), mirroring the OTel GenAI ContentCapturingMode. Off by default; when unset, the env var OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT is parsed using the spec's UPPER_SNAKE tokens.
