Memory Safety in C SSG Without Rust

Is C Unsafe? Only If You Code Unsafe.

Our rules:

1. Every `cax_object_new()` has `cax_object_free()` in same scope
2. No global state - pass CAXObject *ctx
3. Copy, don't reference - copy_all() for context

CAXObject *ctx = cax_object_new();
copy_all(global_data, ctx);
copy_all(ctrl, ctx);
// use
cax_object_free(ctx);

We run valgrind on every build:

==123== All heap blocks were freed -- no leaks are possible

C can be safe. You just need discipline.
