Attribute Macro zero_tracing 

#[zero_tracing]

The Java @ZeroTracing analog as a first-class marker attribute: suppresses the function’s own telemetry (no dataset, no span) while the trace context still flows through for continuity. Order-insensitive — Java does not require a stacking order and neither does this port: write it above or below #[preload], or inline as #[preload(..., zero_tracing)].
