1.448.0

Minor Changes

• #5675 6af1863 Thanks @DanielVisca! - Add trace_propagation_targets: an opt-in allowlist of hostnames or origins that receive a W3C traceparent header on fetch and XMLHttpRequest requests, so backend traces can continue from the browser. Unlisted hosts never get the header, and a traceparent set by the app or by OpenTelemetry instrumentation is never overwritten or duplicated.
