> The Knative consumer filters inbound HTTP headers through {{KnativeHttpHeaderFilterStrategy}}, so Camel-internal headers (the {{Camel*}} namespace) are not mapped onto the message. When a CloudEvent is received in structured content mode ({{application/cloudevents+json}}), {{CloudEventProcessors.decodeStructuredContent}} maps the remaining event fields (extensions) directly onto the message headers without applying any {{HeaderFilterStrategy}}, which is inconsistent with the binary/HTTP-header path.
> This change routes structured-mode extension fields through a {{HeaderFilterStrategy}} before setting them as headers, so {{Camel*}} headers (matched case-insensitively) are filtered consistently on both content modes. Ordinary CloudEvent extension attributes are unaffected.
> Affected: camel-knative-component ({{CloudEventProcessors}} / {{AbstractCloudEventProcessor}}) on main (4.22.0), 4.18.x and 4.14.x. An upgrade-guide note is included.
