/**
 * Performs the one-time WASM module instantiation and resolves to a plain
 * object satisfying {@link CratestackRpcCodec}. Every `encode`/`decode`
 * call on the returned object is synchronous — the async cost is paid
 * once here, never per call, so this composes with the existing
 * (synchronous) `CratestackRpcCodec` contract without changing its shape.
 *
 * Safe to call more than once: later calls resolve once the same
 * in-flight (or already-completed) instantiation settles, they don't
 * re-instantiate the module.
 *
 * @example
 * ```ts
 * const codec = await createCborCodec();
 * const bytes = codec.encode({ hello: "world" });
 * const value = codec.decode(bytes);
 * ```
