Implement a complete Rust reimplementation of the LibJS frontend: lexer, parser, AST, scope collector, and bytecode code generator. The Rust pipeline is built via Corrosion (CMake-Cargo bridge) and linked into LibJS as a static library. It is gated behind a build flag (ENABLE_RUST, on by default except on Windows) and two runtime environment variables: - LIBJS_CPP: Use the C++ pipeline instead of Rust - LIBJS_COMPARE_PIPELINES=1: Run both pipelines in lockstep, aborting on any difference in AST or bytecode generated. The C++ side communicates with Rust through a C FFI layer (RustIntegration.cpp/h) that passes source text to Rust and receives a populated Executable back via a BytecodeFactory interface.
