Create JS library with WASM bindings for ZK inputs generator

[cedoor]

Create a JavaScript library that provides WASM bindings for the new ZK inputs generator crate.
This library will allow the CRISP SDK to pre-compute proof inputs directly in the browser or Node.js environments.

The implementation will start from the existing setup in crisp-zk/crates/js-lib and integrate with the new Rust generator crate.
