Pull request overview
Adds end-to-end Spring Boot integration coverage by running real Spring Boot 3.x/4.x fixtures (downloaded from java-test-applications) and asserting buildpack framework injection behavior (notably java-cfenv, plus combined framework scenarios).
Changes:
- Add real-jar Spring Boot integration tests (SB3 + SB4) including assertions for cloud profile activation and jar/agent presence.
- Add a helper that downloads and pre-explodes Spring Boot fat jars to match CF staging behavior.
- Update docs and a previously dead fixture URL reference.

…oudfoundry#1357) Add integration tests using real fat jars from cloudfoundry/java-test-applications v1.0.0 to verify end-to-end framework injection. Three tests: - SB3 (Boot 3.5, Java 17): java-cfenv 3.x injection, cloud profile verified via RuntimeLogs (boot3 app lacks RuntimeUtils endpoints) - SB4 (Boot 4.1, Java 21): java-cfenv 4.x injection, cloud profile via /active-profiles, java-cfenv presence via /loaded-jars - SB4 combined: java-cfenv + container-security-provider env var + cf-metrics-exporter javaagent — all in one deployment Key design decisions: - Pre-explode fat jars in fixtures_helper_test.go for Docker-mode tests to simulate CF staging (CF bits service extracts pushed jars as zip before running the buildpack). CF-mode tests pass raw jar to cf push. See switchblade#134 for CF-vs-Docker divergence. - Jars sourced from cloudfoundry/java-test-applications@v1.0.0. Also: - Fix dead 404 URL in frameworks_test.go - Update isSpringBootJar comment in spring_boot.go - Update README with correct 5-level -run filter patterns
