release 0.3.0 (#8)

* 0.7 train: the logging bridge on by default, the flat formats, and the split introduction

* the 0.7 engine from crates.io

* release dynamic-config-py and dynamic-config-py-remote 0.3.0

* time and aws-sdk-s3 take their real fixes; the lru ledger speaks of 0.16

* the finalization gate, and each wheel builds in its own target dir

* the group-reload test asserts the tear direction, not the scheduler

   # Cargo updates are grouped: what a wheel links is reviewed as one tree.
