🎯 What's New

Test catalog connection before creation -
Added a catalog connection test API that will validate catalog credentials/configuration before creating the catalog.

Added Usage Telemetry -
Added telemetry tracking for platform information, compaction start and completion events, and catalog additions.
Added Kubernetes-Managed Optimizer -
Added support for running and managing the optimizer through Kubernetes.
Added Catalog Creation Failure Telemetry -
Fusion event to report catalog creation failures with error classifications, without exposing sensitive connection details.

Fixed Prometheus Exporter Startup Failure -
Packaged the Prometheus reporter JAR in the release assembly to prevent AMS startup failures when the Prometheus exporter is enabled.
Fixed Lite Optimization Skipping -
Updated optimization checks to allow Lite optimization to proceed when at least one equality delete file exists and the minor optimization cron is triggered.

Tables that fail during planning are now marked as failed in the UI, and the corresponding AMS error logs are included in the driver logs.
Fixed Partition Compaction Planning -
Updated the planner to include all partitions of an Iceberg table in a single compaction planning run, preventing partitions from being left out.
Fixed Fusion Release Workflow -
Updated the release workflow to support manually triggering container image builds.
Added Fusion Integration Tests -
Added integration tests covering lite, medium, and full optimization, health score evaluation, skipped optimizations, and overall stack readiness.
