v0.10.0

Minor Changes

• 2df8c57: isolation-gate no longer reads layers.json: it packs every packages/* directory that is not private, and a layer's checkout is no longer special-cased. The export leftOutLayerCheckouts is removed with it, and the gate's CLI no longer prints a "leaving out" line. A consumer that still calls leftOutLayerCheckouts must drop the call; a repository that keeps a layer checkout under packages/ and does not want it packed must keep that checkout out of packages/ itself.
