Fix spring-ai plugin: replace Map.of() with JDK 8 API, reset maven.compiler.release

- Replace Map.of() (JDK 9+) with LinkedHashMap in InputMessages.java
- Set <maven.compiler.release /> to cancel parent's --release 8, allowing
  the compiler to resolve java.lang.Record from provided Spring AI classes
- Add spring-ai-1.x-plugin to compiler override allowlist
