Fix build on targets where int32_t is not int (LIST_VALUE)

[jerrytron]

value::set<value_type::int32> is specialized on int32_t, and int32_t is not int on every target — on Xtensa (ESP32) it is long.

The four LIST_VALUE call sites added in #162 pass a bare 0 and the int returned by get_flag_value(), so on those platforms overload resolution selects the primary template rather than the specialization and the build stops:

value.h:132: error: static assertion failed: No setter for this type defined!
    required from list_operations.h:254

It compiles on x86-64 and arm64 Linux/macOS, where int32_t is int, which is why CI did not catch it.

Every other set<value_type::int32> call site in the tree already converts explicitly — numeric_operations.h, container_operations.cpp, runner_impl.cpp — so this just follows the existing convention rather than introducing one.

Found building for ESP32-S3. ctest passes.

Thanks, good catch

Would you mind applying this patch? I do not have access rights to your branch, and my OCD would like a green pipeline.
