* 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.
