JPDFium's published artifacts target JVM 25 and Stirling-PDF's main sources are now compiled with sourceCompatibility = VERSION_25, so JDK 21 is no longer supported. Update header comments and developer-facing docs to reflect the hard floor. - backend-build.yml header: 'JDK 21/25 \xc3\x97 spring-security' -> 'JDK 25 \xc3\x97 spring-security' - AGENTS.md Important Notes: minimum 21 -> requires 25 - DeveloperGuide.md prerequisites + setup steps: drop 'or later, 25 recommended' language, say 'JDK 25' outright.
