Adds multicast group subscription distribution to the DDM exchange protocol with a V4 version bump (frozen V3 types for wire compat). Key changes: - V4 exchange protocol with multicast support (V3 peers are unaffected) - UnderlayMulticastIpv6 validated newtype moved to mg-common (ff04::/64) (moved from rdb types) - MRIB->DDM sync in mg-lower/mrib.rs - OPTE M2P hooks for learned multicast routes (requires OPTE #924) - Atomic update_imported_mcast on Db (single lock for import/delete/diff, which is a bit different from the tunnel work) - Collapsed send_update dispatch - Shared pull handler helpers (collect_underlay_tunnel, collect_multicast) - MulticastPathHop constructor - Some serde round-trip and validation tests, including for version handling Stacked on zl/mrib (MRIB: Multicast RIB implementation [#675](#675)).
