Configuration Cache Support & Thread Safety for Git Pre-push Hook

This PR introduces two important improvements for the spotlessInstallGitPrePushHook task:

What’s Changed

• Configuration Cache Compatibility
  • Refactored the Gradle task to avoid calling project during task execution.
  • Uses Property to inject the project root directory in a cache-safe way.
  • Task is now compatible with org.gradle.configuration-cache=true
• Parallel Execution Safety
  • Added synchronization (synchronized lock) to prevent race conditions during parallel task execution.
  • Ensures that the hook is only installed once when tasks run in parallel (e.g., via --parallel or multi-project builds).

Why

• Without these changes, running the task with configuration cache enabled caused build failures.
• Running the task in parallel previously led to flaky behavior such as:
  • "Failed to create pre-push hook file"
  • Partial or corrupted hook installation.
• These fixes make the feature stable and safe in all Gradle environments, including CI pipelines.
