Create E2E Fixture

Steps

1. Identify the test case: What behavior needs testing across language bindings?

2. Choose category: smoke, basic, parsing, edge-case, error-handling, or platform-specific.

3. Write fixture JSON:

   {
     "id": "descriptive_snake_case_name",
     "category": "basic",
     "description": "Tests that X produces Y",
     "source_code": "input data or code",
     "assertions": {
       "tree_not_null": true,
       "expect_error": false
