feat(pkg): phase 15 - a package can carry a native library

Browse source 
native "<target>" "<path>" in a package's package.ludic; the compiler records the libraries of
every package a program imports and writes them into the IR (; ludic-native:), so ludicc -o,
ludic build, ludic test and ludic bundle all link one list. macOS: an rpath to the package and to
Contents/Frameworks, where ludic bundle copies and signs each library and drops the build
machine's rpath. Windows: the import library, the .dll copied beside the exe (--natives-out for
the bundle). tools/native/lib.sh builds from a pinned, checksummed source with clang on both
machines; ludic.nativeecho is the worked example; the shim rules are in packages/README.md.
Linked at build time rather than dlopen (docs/PACKAGES.md says why). Reseeded.
