//! PluginConverter: Converts PluginTransform MutationSpec to WASM plugin execution
//!
//! This is a skeleton implementation for future WASM plugin support.
//! The actual WASM runtime integration will be implemented when the
//! plugin infrastructure is ready.
//!
//! See docs/wasm-plugin-architecture.md for the full design.
