This is an initial AI-assisted review.

The OpenRemote 1.30.0 migration is incomplete in the development profiles, which still extend the 1.28.1 deploy.yml. The newly added dependency-check task also references a script that is not present in the repository.

The Keycloak theme-development profile additionally drops the theme-cache configuration as part of the Keycloak 26.7 cleanup. That matches the upstream dev-testing.yml change, but this profile has a different purpose and still mounts custom themes, so it is worth confirming that the removal is intentional.

CI is currently failing spotlessGradleRootCheck on the new project.gradle block, so the remaining build and test steps did not run.
