Module fixtures 

Sexpr-based test fixtures for backends and cross-repo tests.

The backend crates historically hand-constructed IacResource and IacAttribute test fixtures as Rust literals. When the IR grew new fields (json_encoded, optional, update_only) those literals went stale, silently in some repos and loudly in others. Fixtures stored as canonical sexpr text avoid that drift: the IR owns the sexpr shape, every consumer loads through the same canonical path, and adding a field only requires editing the fixtures once.

Pattern

Write a fixture:

use iac_forge::testing::fixtures;
use iac_forge::testing::test_resource;

let resource = test_resource("widget");
fixtures::save_resource(&resource, "tests/fixtures/widget.sexpr").unwrap();

Load it back in tests:

use iac_forge::testing::fixtures;

let resource = fixtures::load_resource("tests/fixtures/widget.sexpr").unwrap();
assert_eq!(resource.name, "widget");

String-based loaders (_str variants) are equivalent but skip disk I/O — useful for tests that embed the fixture via include_str!.
