Activate 5 dead frameworks and centralize framework/JRE registration
This commit activates 5 fully-implemented but unregistered frameworks that were previously unreachable dead code, and eliminates significant code duplication by centralizing component registration logic. Activated Frameworks: - ContainerCustomizer: Tomcat configuration customization for Spring Boot WAR apps - JavaMemoryAssistant: Memory leak detection and heap dump management - MetricWriter: Micrometer metrics export for Spring Boot applications - ProtectAppSecurityProvider: Key management and security certificates - SeekerSecurityProvider: Synopsys Seeker IAST agent Code Duplication Eliminated: - Created RegisterStandardFrameworks() method in framework.go to centralize 43 framework registrations previously duplicated in supply.go and finalize.go - Created RegisterStandardJREs() method in jre.go to centralize 7 JRE registrations previously duplicated in supply.go and finalize.go - Removed ~146 lines of duplicate registration code across both phases JRE Detection Logic Fixed: - Fixed Registry.Detect() to return error when no JRE found (not nil) - Fixed OpenJDK.Detect() to only detect when explicitly configured via env vars - Added test coverage for explicit JRE selection (SapMachine over OpenJDK default) - Updated tests to properly use SetDefault() mechanism Impact: - Net reduction: ~66 lines of code - All 28 JRE unit tests pass - All Java buildpack unit tests pass (containers, frameworks, supply, finalize) - 81/87 integration tests pass (5 pre-existing Groovy failures unrelated to changes) - No new dead code introduced
