- package.json / package-lock.json: package name "numolus"
- README: new title, drop the "Case- und Designstudie" framing, update
test count (331 -> 528)
- localStorage keys renamed to numolus:doc:v2 / numolus:theme; the old
numbers-study:* keys are still read as a fallback so existing documents
and theme choices survive the rename
