Greptile Summary

This PR adds support for the newly introduced @sim/testing package (from PR #2586) to both Docker build configurations. The changes ensure that the testing package's dependencies are properly installed during the Docker image build process by including its package.json in the dependency resolution stages.

Changes made:

• Added packages/testing directory creation in the deps stage
• Copied packages/testing/package.json in both deps and builder stages for app.Dockerfile and realtime.Dockerfile
• Maintains consistency with existing pattern used for packages/db

Impact:

• Enables the monorepo workspace to recognize and install dependencies for the testing package during Docker builds
• Ensures tests can run successfully in containerized environments
• No functional changes to application runtime behavior

Confidence Score: 5/5

• This PR is safe to merge with no risk
• The changes are straightforward, mechanical additions that mirror the existing pattern for packages/db. They're necessary to fix Docker builds broken by PR feat(tests): added testing package, overhauled tests #2586, which added the testing package. All changes follow established conventions and don't modify any runtime logic
• No files require special attention

Important Files Changed

Filename	Overview
docker/app.Dockerfile	Added packages/testing directory creation and package.json copy statements in deps and builder stages to support new testing package
docker/realtime.Dockerfile	Added packages/testing directory creation and package.json copy statements in deps and builder stages to support new testing package
