In Bazel, when you use Starlark transitions (which change the configuration of a target), the output directory name is updated with a hash (the ST-hash) to keep the files separate. However, there was a bug
where Starlark flags set by Platforms (using the platform() rule) weren't being correctly tracked during these transitions. This caused issues where flags weren't "reset" or "cleaned up" properly, leading
to inconsistent build outputs.
