Summary

Closes CI: CheckGenerated runs build_runner twice per pipeline — eliminate duplicate work (#492)
Replaces the git-snapshot + second run in with a direct file comparison against the output of
compares committed generated files against the freshly built ones from the already-shared layer
Removes ~3 min from every CI pipeline run

How it works

Previously ran independently, so Dagger could not share its cache with . Now it:

Calls to get freshly generated files (reusing the cached Dagger layer)
Mounts committed source at and fresh output at
Runs to detect staleness

Test plan

runs without error when generated files are up to date
fails with a clear message when a file is stale
CI pipeline shows only one execution in the Dagger trace
