-feat: W3C-compatible distributed tracing
-
-- Add `inject`/`extract` APIs for distributed tracing across service boundaries
-  (`span.inject(carrier)`, `injectTraceContext()`, and
-  `extractTraceContextFromHeaders(headers)`),
-  implementing the [W3C Trace Context](https://www.w3.org/TR/trace-context/) and
-  [W3C Baggage](https://www.w3.org/TR/baggage/) specs. `startSpan({ parent })` now
-  accepts the opaque context returned by `extractTraceContextFromHeaders` in
-  addition to an exported span slug.
-- Default to OpenTelemetry-compatible hex span/trace IDs (and V4 span-component
-  export). Set `BRAINTRUST_LEGACY_IDS` to opt back into legacy UUID IDs (and V3
-  export). `BRAINTRUST_OTEL_COMPAT` continues to force hex IDs and takes
-  precedence over `BRAINTRUST_LEGACY_IDS`.
-
-Note: The deprecated `span.export()` / `startSpan({ parent: <slug> })` path remains
-supported and links correctly across the UUID and hex formats.
