Fix ForgeGradle 7 legacy CLI setup and build

[SkyBlade1978]

Summary

• run Gradle 9 / ForgeGradle 7 on a pinned Java 17 daemon while retaining the Java 8 compilation toolchain for Minecraft 1.10.2
• add the legacy lwjgl_util compile-only dependency omitted from Mavenizer's compile classpath
• correct mcmod.info expansion, runtime mod ID, release version, and archive naming
• generate Eclipse launch configurations on Buildship sync and document the current CLI setup commands
• align build and release workflows on JDK 17

Failures reproduced

• Gradle refused to start while JAVA_HOME pointed to Java 8
• compileJava could not access org.lwjgl.util.vector.Vector3f
• processResources failed because mcmod.info referenced undefined description and version expansion properties

Verification

• gradlew.bat clean build eclipse genEclipseRuns --no-daemon
• passed in the working checkout with Java 8 still configured as JAVA_HOME; Gradle selected the Java 17 daemon from the checked-in criteria
• passed from an isolated project copy and empty GRADLE_USER_HOME
• produced iron-age-furniture-0.2.0.5.jar plus client/server Eclipse launch configurations
