0027 stays Draft — its PR (#95) is not merged.

Renames the file and rewrites the body around what actually shipped:
class-based BottleBackend ABC (not a free create_docker_bottle

subpackage layout, env.py reshaped into a backend-neutral ResolvedEnv,
and PipelockProxy split between top-level and backend/docker/.
