Subject: [PATCH] feat: dockerize + switch to hatch-vcs versioning

- Switch version source to hatch-vcs (driven by git tags). __init__.py
  reads from the generated _version.py with importlib.metadata fallback
  for editable installs.
- Add Dockerfile based on python:3.13-slim-bookworm with all runtime
  tools (dar, par2, genisoimage, growisofs, dvd+rw-tools, udisks2,
  lsof, eject, mount). Version is injected via
  SETUPTOOLS_SCM_PRETEND_VERSION build-arg, so .git/ does not need to
  be in the build context.
- Add docker-publish workflow that builds linux/amd64 + linux/arm64
  images on v*.*.* tag push and publishes them to ghcr.io with semver
  tag fan-out (5.0.0, 5.0, 5, latest).
