fix: use configureEach instead of all for JavaCompile tasks

[tinder-ryantrontz]

Problem

scip-java index crashes on Gradle 8.12.1 projects that define custom source sets (e.g. intTest) with a Java toolchain:

Caused by: java.lang.IllegalStateException:
  The value for task ':accountintegrity-models:compileIntTestJava'
  property 'javaCompiler' is final and cannot be changed any further.

  at org.gradle.api.plugins.JavaBasePlugin.lambda$createCompileJavaTask$6(JavaBasePlugin.java:229)

Root Cause

SemanticdbGradlePlugin uses the eager .withType(JavaCompile).all {} API inside afterEvaluate. This forces immediate realization of lazily-registered JavaCompile tasks. During realization, the plugin reads javaCompiler via .getOrNull(), which triggers Gradle's finalizeValueOnRead — locking the property before JavaBasePlugin can set its convention().

Fix

Replace .all {} with .configureEach {} (line 107 of SemanticdbGradlePlugin.scala). This defers the configuration action until Gradle has fully initialized each task.

Note: the Scala plugin path on line 222 already uses .configureEach {} correctly.

Verification

• New test lazy-sourceset-with-toolchain reproduces the scenario (custom intTest source set + toolchain)
• Full Gradle_8_BuildToolSuite passes (16/16, 1 skipped for JDK version)
• Tested the built binary against a production Gradle 8.12.1 monorepo (40+ modules) — BUILD SUCCESSFUL, index.scip generated
