The Rust bytecode codegen was missing a TDZ check before assigning to local let/const variables in simple assignment expressions (a = expr). The C++ pipeline correctly emits ThrowIfTDZ before the store to ensure temporal dead zone semantics are enforced. Add an emit_tdz_check_if_needed helper matching the C++ equivalent, and call it in the simple assignment path.
