...except for one method
runBuilder, its implementation is moved tobuild_runner_corewithout changes inrun_builder.dart. A forwarding method is left inpackage:buildand marked deprecated.NoOpStageTrackeris an implementation detail ofrunBuilder, a default for one of the args, so it moves with it tobuild_runner_core.No other changes to code besides updating imports as needed, and moving tests to where the impls now live.
