feat: Add Java 17+ and Spring Boot 3 code review guide

- Create `reference/java.md` with guidelines for modern Java (Records, Switch, Text Blocks), Spring Boot 3 (DI, Configuration), JPA (Performance, N+1), and Concurrency (Virtual Threads). - Update `SKILL.md` to register the Java guide for on-demand loading. - Update `README.md` to include Java in supported languages and key topics.
