- Turn the collaboration plan into module docs (Doku/modules/collaboration.md)
describing the implemented state; remove Doku/plans
- Header version comes from the build: git tag via APP_VERSION (CI passes
it for tag builds), otherwise "<package version>-dev"; package 0.2.0
- Sample data (setup option and demo mode): six inbox thoughts, two task
lists with Kanban states, subtasks and due dates, shopping and packing
lists, three notes in folders incl. a long nested outline; demo mode
shares the note and two lists with user/user
- e2e/screenshots.sh renews the README screenshots from demo data
- README: live collaboration, editor sharing, image tags, version badge
