Add support for DYNAMIC_GROUPS track extension and NEW_GROUP_REQUEST (NGR) parameter forwarding through the relay. - MoQForwarder tracks outstanding NGR and clears it when upstream largest group advances; exposes tryProcessNewGroupRequest() to consolidate the extract/gate/set/fire pattern used at all call sites - MoQRelay forwards NGR upstream via REQUEST_UPDATE when a downstream subscriber requests a new group on an existing upstream subscription; passes NGR through on new upstream subscribes without an extra update - Track status returns local forwarder state when an active subscription exists, falling back to upstream only when no subscription is found Co-Authored-By: Alan Frindell <8259689+afrind@users.noreply.github.com>
