Pull request overview

This PR reduces GitHub Actions Gradle cache churn and aligns build-cache behavior with Develocity by limiting which CI jobs can write caches and by ensuring default-branch CI builds prioritize populating the authenticated Develocity remote build cache.

Changes:

• Update settings.gradle.kts to disable the local Gradle build cache on authenticated CI builds of main, and switch remote cache configuration to remote(develocity.buildCache).
• Make most auxiliary workflows (CodeQL, benchmarks, release, scheduled audits, etc.) use setup-gradle in read-only cache mode.
• Restrict GitHub Actions cache writes in the main build matrix to a single Java 25 job per OS and exclude caches/build-cache-1 from those writer snapshots.
