Documents now live in an IndexedDB library instead of a single
localStorage slot: each has its own ?doc=<id> URL, a title (editable in
the toolbar, used for export file names) and appears in Datei ›
Dokumente (open, rename, duplicate, delete). New/sample/import create
new documents instead of replacing the open one. Tabs stay in step via
BroadcastChannel. The old localStorage document is migrated once.

Datei › Speichern writes a .num file: a ZIP (fflate) laid out like
OpenDocument -- an uncompressed "mimetype" entry first
(application/x-numolus), meta.json (format version, ISO 8601 creation
time) and document.json, the same JSON the .json export writes. Opening a
.num (file dialog or drag & drop) unpacks it and offers the same
replace/append choice as a .json. Non-ZIPs, foreign ZIPs, a missing
document.json and a newer format version fail with a clear message.
The zip code is loaded on first use, like xlsx, so the main bundle does
not grow.

- 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
