(PRD 0024).

The bundle image (built by Dockerfile.sidecars, PRD 0024 chunk 1)
runs pipelock + egress + git-gate + supervise as one container
per bottle under a small Python init supervisor. As of chunk 5
the bundle is the only shape — the legacy four-sidecar topology
and its `BOT_BOTTLE_SIDECAR_BUNDLE` feature flag are gone."""
