Integrates origin/main (per-program-crate refactor) and re-homes the cross-zone messaging feature onto it. BREAKING CHANGE: Genesis state root changes. This registers six builtin programs (cross_zone_outbox, cross_zone_inbox, ping_sender, ping_receiver, bridge_lock, wrapped_token) and seeds their genesis accounts (the wrapped_token authorized minter config, the per-zone inbox config, and optional bridge-lock holdings). Building the new cores alongside the existing builtins also enables serde/alloc for the shared programs build, regenerating every builtin program image id. All nodes must upgrade together.
