- Remove C emission, debugging options, and automatic backend fallback.
- Complete LLVM lowering and native bootstrap coverage across supported targets.
- Link executables and libraries with precompiled C runtime packs, including iOS and Android.
- Preserve async factory results and mixed table layouts through inference and destructuring.
- Support checked Map and Object.fromEntries construction with native weak collections.
- Keep native weak-key lifetimes and engine-backed collection identities intact.
