Function plan_channel_addresses_like_cpp 

pub fn plan_channel_addresses_like_cpp(
    facts: ChannelAddressPlanFacts,
) -> ChannelAddressPlan

Plan the common C++ Connector address stages for Platform and Broker.

The emergency fallback is Rust’s compatibility escape hatch for a missing dynamic catalog. It is only exposed when every C++ strategy stage is empty, so it cannot revive the retired previous-address priority path.
