The org.jetbrains.intellij 1.x plugin is EOL: it uses Gradle-internal API removed in Gradle 9 and cannot build against IDE targets >= 2024.2. Replace it with org.jetbrains.intellij.platform 2.x using the unified intellijIdea distribution (IC is no longer published since 2025.3), raise the Java target to 21 as required by modern IDE targets, and declare sinceBuild 261. Ignore the plugin's .intellijPlatform cache dir. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Lombok 1.18.34 crashes javac 25 with ExceptionInInitializerError during compileTestJava. A toolchain makes Gradle compile with a discovered JDK 21 regardless of the JVM that launches the build. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- IntelliJ Platform Gradle Plugin 2.11.0 -> 2.18.1 - JUnit Jupiter/Platform 5.10.3/1.10.3 -> 6.1.2 (unified versioning) - Hamcrest 2.2 -> 3.0 - Lombok 1.18.34 -> 1.18.46 (adds JDK 25 javac support) - Replace toolchain pin with source/target compatibility 21 so the build runs on the default JDK 25 while emitting Java 21 bytecode Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Summary
./gradlew buildwas broken after upgrading the toolchain:org.jetbrains.intellij1.x (every version, incl. 1.17.4) depends on a Gradle-internal class (DefaultArtifactPublicationSet) that Gradle 9 removed, and 1.x also cannot build against IDE targets ≥ 2024.2. This PR completes the upgrade by migrating to JetBrains' successor plugin.Gradle wrapper 9.6.1 (first commit)
gradlew/gradlew.batscripts regenerated via./gradlew wrapperso they match the 9.6.1 properties file (the manual properties-only edit had left them at 8.4).Build migration (second commit)

sinceBuild = 261means users on IDEs older than 2026.1 stop receiving updates (intentional).No production or test source changes were needed — everything compiles cleanly against the 2026.1 platform.
