* feat: ship the self-hosted native scriptc CLI
- Run the shared compiler and CLI natively, including library builds and compile-time evaluation.
- Install native platform packages and ship relocatable standalone distributions.
- Preserve program semantics and reuse validated build artifacts for fast rebuilds.
* fix: complete native CLI integration and validation
- Preserve library diagnostics and run recursive compiler work on the main stack.
- Restore packaged helper permissions and exercise native npm and Wasm library builds.
- Recover interrupted Sandbox status probes within the original command deadline.
- 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.
- Run the production LLVM backend natively and reproduce its output across compiler generations.
- Replace unchecked emitter contexts with explicit shared state and callback hosts.
- Preserve NaN in serialized IR and respect optional record storage during spreads.
- Compile production IR serialization and runtime dependency scans on both native backends
- Support native JSON callbacks and checked records with unknown payloads
- Verify native IR round trips and executable generation with focused sanitizer coverage
