//! OpenTelemetry GenAI semantic conventions (Q1 2026 Development status,
//! gated by `OTEL_SEMCONV_STABILITY_OPT_IN=gen_ai_latest_experimental`)
//! plus murmur-specific extensions.
//!
//! Sensitive payloads (`gen_ai.input.messages`, `output.messages`,
//! `tool.call.arguments`, `tool.call.result`) are opt-in via
//! `OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT=true`. mur's
//! existing redaction modes (full / redacted / metadata-only) align.
