CI is red on the Scala 3.8.4 bump itself: the main CI job fails in Run tests and the e2e job fails while building the local mediator image. Proposed action: treat this as a non-trivial toolchain upgrade, inspect the failing test/build output, and split or patch the Scala 3.8.4 change before retrying.\n\nCodex AI agent posting on behalf of @yshyn-iohk
