A :jolt/native spec can now carry a :static archive; `jolt build` links it
into the executable, so the app calls the C code with no shared object on the
target. --dynamic (or :jolt/build {:dynamic-natives true}) keeps the old
runtime load-shared-object behavior; a spec with no :static is unchanged.
The cc link force-loads the archive (-force_load on macOS, --whole-archive on
Linux) and exports the executable's symbols (-rdynamic on Linux) so the baked-in
symbols resolve via (load-shared-object #f) + foreign-procedure at startup. Build
step 1 evaluates the app's foreign-procedure forms in-process, so a static
archive is preloaded there as a throwaway shared object to resolve them.
The distributed self-contained joltc has no external cc/Chez but must build these
apps, so it now bundles the Chez kernel (libkernel.a + scheme.h) and the launcher
source and re-links a custom stub with the archives baked in — needing only a
system cc, no Chez. run/repl skip static-only specs (nothing to load); keep a
:darwin/:linux candidate to use such a lib interpreted.
Adds static-native-smoke (cc path) to ci and a static phase to the joltc
self-build smoke (distributed path).
