Chris Tate 3f66c8e20b Make LLVM the sole production backend

- 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.

External program object

This macOS arm64 example links a scriptc program object, a small C FFI implementation, and the exact installed precompiled runtime pack. It uses no scriptc cache path.

$ clang -target arm64-apple-macosx14.0.0 -O2 -c native.c -o native.o
$ scriptc build main.ts --ffi ffi.json --print=native-link-info -o app.o > link-info.json
$ node link.mjs cc link-info.json app-cc
$ ./app-cc
42
$ node link.mjs ld link-info.json app-ld
$ ./app-ld
42

cc uses the C compiler as a linker driver. ld links the same precompiled runtime objects directly with the selected Apple SDK. The object defines main; it is a complete program object, not a library to load into another process. Use scriptc build --lib --profile ... for a host-callable static library.

The external object ABI is experimental. Always consume the runtime pack at the exact runtime_pack.version reported by the same scriptc installation. The object requires scr_runtime_abi_v4, so a mismatched runtime fails during the link instead of starting with an incompatible ABI.
