Add Gradle caching and attempt to de-flicker the Windows build#894
Conversation
The Windows job intermittently failed with "Connection reset by peer" and exit value 100 from the Gradle test executor — symptoms of an out-of-memory crash in the test JVM under TestKit + parallel workers on RAM-constrained Windows runners. - Cap test executor heap to 1g on Windows so an over-budget run throws a clean OOMError instead of crashing the JVM natively. - Limit --max-workers=2 on the Windows job to reduce concurrent test JVMs and TestKit child daemons. - Add the org.gradle.test-retry plugin and enable 2 retries when CI=true to absorb residual TestKit/file-locking flakes; local runs unaffected. - Scope the JVM 11 Kotlin target override to compileKotlin only, silencing the "Inconsistent JVM-target compatibility" warning between compileTestJava (21) and compileTestKotlin (11). Production bytecode is unchanged. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
