+Remove structuredOutput model configuration option
+
+**Breaking Change**: The `structuredOutput` model configuration has been removed from the `Models` type. All code generation now uses the `base` model configuration.
+
+**Migration**: Remove any `structuredOutput` configurations from your projects, agents, and sub-agents. The framework will automatically use the `base` model for all operations, including data components.
+
+Before:
+```typescript
+models: {
+  base: { model: "anthropic/claude-sonnet-4-5" },
+  structuredOutput: { model: "openai/gpt-4.1-mini" },
+  summarizer: { model: "anthropic/claude-haiku-4-5" }
+}
+```
+
+After:
+```typescript
+models: {
+  base: { model: "anthropic/claude-sonnet-4-5" },
+  summarizer: { model: "anthropic/claude-haiku-4-5" }
+}
