ECMAScript hoisting keeps the LAST function declaration with a given name. The Rust scope_collector and script GDI extraction implemented this with a single reverse scan that pushed first-seen entries, which left the resulting list in REVERSE source order. The C++ side then iterated `m_functions_to_initialize.in_reverse()` to undo that. Switch the Rust side to a two-pass forward scan that records the last position per name and emits entries in source order, and drop the matching `.in_reverse()` calls in Script.cpp and AbstractOperations.cpp. Same hoisting semantics; NewFunction emission and global property iteration order now follow the source. The HashMap that tracks last positions is keyed on `SharedUtf16String`, so each insert is a refcount bump on the AST's existing Rc instead of a deep `Vec<u16>` clone. Add bytecode tests at script and nested-function scope that exercise multiple declarations and a duplicate name to pin the new ordering.
