Add Switchblade integration tests for Java buildpack
Implement Go-based integration tests using Cloud Foundry Switchblade framework to replace external system tests with in-repo testing infrastructure. Tests cover: - Tomcat container with JRE selection (Java 8, 11, 17) - Spring Boot applications with auto-reconfiguration and Java CFEnv - Java Main applications with custom arguments and JAVA_OPTS - Offline/cached buildpack mode - Memory calculator configuration The test suite supports both Cloud Foundry and Docker platforms and runs in parallel for improved test execution time. Test Results: - All 13 integration tests passing - Average execution time: ~54 seconds (parallel execution) - Validates buildpack behavior with actual deployments Files Added: - src/integration/*_test.go - Test implementations - src/integration/init_test.go - Test suite initialization - src/integration/README.md - Documentation - scripts/integration.sh - Test runner script - go.mod, go.sum - Go dependencies
