Fixture Schema Design

• Fixture fields: id (unique snake_case), category, description, language, source_code, assertions, skip, tags
• Assertion types: equality (field_equals), contains (root_contains_node_type), boolean (tree_not_null), count (root_child_count_min)
• Skip conditions: requires_language, platform — generators emit language-native skip annotations
• IDs unique across ALL fixture files, used as test function names
• One category per file (smoke.json) or organized in subdirectories (fixtures/smoke/)
