/**
 * SDK 2.0 tracing layer — public re-exports.
 *
 * Same shape as 1.x for consumer ergonomics; the underlying span vocabulary is
 * QAR-native (`qar.client.*` per the design doc). Internal per-public-API
 * spans are emitted by the client itself (`src/observability/spans.ts`); the
 * `SdkTracer` exported here is the observer-style helper for consumers
 * tracing a `client.receive()` tap or a stand-alone `TaskEvent` stream.
