Description

Improves our published docker images:

• Multistage Dockerfile gives cleaner final container environment
  • also about 100mb smaller
• non-editable app package installation makes final container runtime environment better
• more professional running bunny app entrypoints directly (not via uv run)
• change from ENTRYPOINT to default CMD retains prior default behaviour (bunny-daemon) but allows more flexible CLI usage
  • Makes the image more compatible with certain execution environments, e.g. CWL, Bacalhau...

This PR includes a version bump so that we can immediately get newly version tagged releases for the new images.
