Implement a `client` crate that wraps the `libchat` context behind a simple `ChatClient<D>` API. The delivery strategy is pluggable via a `DeliveryService` trait, with two implementations provided: - `InProcessDelivery` — shared `MessageBus` for single-process tests - `CDelivery` — C function-pointer callback for the FFI layer Add a `client-ffi` crate that exposes the client as a C API via `safer-ffi`. A `generate-headers` binary produces the companion C header. Include two runnable examples: - `examples/in-process` — Alice/Bob exchange using in-process delivery - `examples/c-ffi` — same exchange written entirely in C; smoketested under valgrind (to catch memory leaks) in CI iterates: #71
