PR Summary

Low Risk
Build-only Dockerfile change with no runtime auth, data, or application logic impact; reduces risk of silently wrong prune targets during image builds.

Overview
The pruner stage no longer calls turbo prune sim --docker with a fixed name. It reads apps/sim/package.json at build time and passes that name to turbo prune.

That matters because packages/sim-cli is also named sim, so the old target could prune the CLI workspace instead of @sim/app after renames or naming collisions—breaking dependency install and the rest of the image pipeline.

A related comment now refers to turbo prune generically instead of turbo prune sim.

Greptile Summary

The PR fixes Docker pruning by resolving the application workspace name from apps/sim/package.json instead of using the colliding sim CLI package name.

• Reads the application package name during the pruner stage.
• Passes the resolved @sim/app name to turbo prune.
• Updates the dependency-stage explanation to avoid referring to the obsolete hard-coded target.

Confidence Score: 5/5

The PR appears safe to merge, with the application package now selected correctly during Docker pruning.

The pruner stage has Bun available, runs from the copied repository root, resolves the existing @sim/app manifest name, and passes it as one quoted argument to Turbo.

Important Files Changed

Filename	Overview
docker/app.Dockerfile	Correctly resolves and quotes the application manifest name before pruning; no actionable issue was identified.
