+Tests for InputPreprocessor.create_processor().
+
+Why mock:
+  - ModelConfig, ReasoningParserManager, ToolParserManager, and concrete processor
+    classes all depend on model files or external resources not available in tests.
+    We mock them at the import boundary to test InputPreprocessor's routing logic.
