Description

### Apache NetBeans version

Apache NetBeans 17

### What happened

Methods annotated with CDI @PostConstruct and @PreDestroy are reported as unused methods by the IDE Hints. Methods annotated with @PostConstruct and @PreDestroy are intended to be invoked by the CDI Framework implementation, not by the programmer. This error does not occur in 12.6 version.

### How to reproduce

1. Create a new Jakarta 10 Web Profile maven project;
2. Define a new CDI Managed Bean and add a private void method annotated with @PostConstruct and add a private void method annotaded with @PreDestroy;
3. The IDE wil hint these methods as "unused methods";

### Did this work correctly in an earlier version?

Apache NetBeans 12.6 or earlier

### Operating System

Oracle Linux 9.1 x64

### JDK

OpenJDK 11

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else

_No response_

Research direction

No source file or test is named. Reproduce the warning in a Jakarta 10 Web Profile Maven project with private CDI lifecycle methods, then trace the IDE Hints logic that reports unused methods and its handling of @PostConstruct and @PreDestroy. Done means both annotations no longer produce unused-method warnings, with a regression test if the relevant test area is identified.
