refactor: enhance model configuration and plugin execution

- Simplified the `createModel` function to directly accept the `ModelConfig` object, improving clarity.
- Updated `createBaseModel` to include `extraModelConfig` for extended configuration options.
- Introduced `executeConfigureContext` method in `PluginManager` to handle context configuration for plugins.
- Adjusted type definitions in `types.ts` to ensure consistency with the new configuration structure.
- Refactored plugin execution methods in `PluginEngine` to utilize the resolved model directly, enhancing the flow of data through the plugin system.
