java: a starter's AutoConfiguration.imports and spring.factories are not read, so the classes they register are neither beans nor entry points #1392

A Spring Boot starter registers its classes in META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports and META-INF/spring.factories. Neither file is read. A class named only there has no entry point, no instantiation and no bean definition, while a class named in a META-INF/services file of the same module is a service_loader entry point with its constructor reached. Measured on 0.1.3 at 0df257c.

src/main/resources/META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports
    example.WidgetAutoConfiguration
src/main/resources/META-INF/spring.factories
    org.springframework.context.ApplicationContextInitializer=example.WidgetInitializer
src/main/resources/META-INF/services/example.Plugin              # control
    example.WidgetPlugin

@AutoConfiguration
public class WidgetAutoConfiguration {
    public WidgetAutoConfiguration() { WidgetWire.open(); }
}
public class WidgetInitializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
    @Override public void initialize(ConfigurableApplicationContext ctx) { WidgetWire.init(); }
}
public interface Plugin { void start(); }
public class WidgetPlugin implements Plugin {                    // control
    public WidgetPlugin() { WidgetWire.plug(); }
    @Override public void start() { }
}
public class WidgetWire { public static void open() { } public static void init() { } public static void plug() { } }

Actual entry_points: WidgetPlugin|service_loader and start|service_loader only. ext_type_instantiated holds WidgetPlugin only and ext_bean_def is empty. impact WidgetWire.open reaches the auto-configuration constructor only through the generic "nothing resolved calls them" fallback, the label an unused method gets.

Expected: WidgetAutoConfiguration and WidgetInitializer are registered types as WidgetPlugin is, and WidgetAutoConfiguration is a bean.

Root cause

The parser reads only META-INF/services/<binary-name> (parser/src/constants/consts.ts:176-185), and the engine's only registration-file consumer feeds cfg_registered_type(t, "service_loader") at graph/java/engine/config-resolution/services.dl:47. No relation carries either Spring Boot file. Separately, graph/java/engine/config-resolution/knobs.dl:16-20 lists Configuration as a bean stereotype but not AutoConfiguration, which is meta-annotated @Configuration.
