Error message:

IdeaLoggingEvent[message=null, throwable=java.lang.IllegalArgumentException: Cannot add an action twice: Upgrade Java Runtime and Frameworks (Upgrade Java runtime and framework versions) (com.microsoft.azure.toolkit.intellij.appmod.javaupgrade.action.JavaUpgradeContextMenuAction)

Start by reading UpgradeActionRegistrar.discoverAndRegisterAction and tryAddToGroup, especially line 100, then inspect JavaUpgradeContextMenuAction. Reproduce in IntelliJ 2026.1 with plugin 3.97.3 on Windows 11 and verify that registering the upgrade action no longer raises the duplicate-action exception.
