Derive the release changelog path from the release version instead of
hardcoding 3.2.md, so the workflow keeps working after 3.3 ships. Add
docs/changelog/3.3.md summarizing the 3.3.0 section of CHANGELOG.md.
Fix docker-compose.yml's PGID/PUID falling back to shell substitution
that never runs in a compose file, using numeric defaults instead, and
drop the obsolete top-level 'version' key. Fix README's Python badge to
3.13 to match backend/pyproject.toml's requires-python.
