"""Publish the toolchain to the Hub in a single commit.

The Hub allows 1000 API requests per five minutes across the whole account,
and the upload lanes are already spending most of that budget on data. Sending
the toolchain one file at a time competes with them for no reason: this batches
every changed file into one commit, which is one round trip regardless of how
many files moved.
