Highlights
v3.0.0 is a full redesign of zerokit's internals, public API, and FFI/WASM boundaries. The headline change is that mode selection moved from compile-time feature flags to runtime and type-level configuration.
There are no longer stateless, multi-message-id, or tree-backend cargo features: state is now a type-state on RLN<State, ZkProof> (Stateful<T> / Stateless), the tree backend is a plain type parameter (FullMerkleTree, OptimalMerkleTree, PmTree), and single vs. multi message-id is a runtime enum on RLNWitnessInput / RLNProofValues.
The RLN object is constructed through a builder (RLNBuilder::stateful(tree) / RLNBuilder::stateless()), witnesses are built with typed builders (RLNWitnessInput::new_single() / new_multi()), serialization is unified behind a single Serialize/Deserialize trait family in protocol/serialize.rs, and the FFI surface was rewritten against the new API.
This is a breaking release for every downstream consumer.
