exp-6 C FFI Scalar Imports Alpha Fixture

This fixture is experimental compiler-supported coverage for .llm/EXP_6_C_FFI_SCALAR_IMPORTS_ALPHA.md.

It is current compiler support after matching Slovo and Glagol exp-6 gates.

The fixture covers one imported C function:

(import_c c_add ((lhs i32) (rhs i32)) -> i32)

The Slovo wrapper calls it only inside lexical unsafe:

(unsafe
  (c_add 40 2))

slovo.toml makes the fixture usable through project-mode native build gates. The top-level test intentionally exercises the exp-6 test-runner boundary: the interpreter-style test runner must report that C imports are unsupported for direct test execution, while hosted native build uses the local c_add.c companion as an explicit link input.

No pointer types, allocation, deallocation, raw-memory operations, ownership or lifetime model, generated header, library output, C exports, or stable ABI promise is part of this fixture.
