…iler Warnings (#3302) This PR addresses the concurrency issues that emerged in the console messages and runtime statistics Iceberg tables following the integration of PRs #3286 and #3281. The aggressive removal of old snapshots and metadata in those earlier changes caused failures during concurrent read and write operations. To resolve this, snapshots and metadata are now lazily removed—triggered either when a workflow restarts or upon lifecycle expiration. Additionally, this update removes the Scala compiler warnings that were previously occurring during code compilation.

This PR addresses the excessive storage consumption caused by metadata generated when storing console messages into the Iceberg table. This simple workflow produced 1.2GB of files: console message data and related Iceberg metadata.
The root cause is similar to the issue addressed in PR #3281 — the frequent commits to the Iceberg table result in excessive metadata generation.
To mitigate this, I reduced the frequency of commits, which significantly reduces the amount of generated metadata.
After this change, the same workflow produces only 184KB of files, representing a dramatic reduction in storage usage.
