All editors now work on a server document at the same time instead of
taking turns behind an edit lock.
- The document's content is a sequence of Yjs updates (document_updates);
DocumentChannel stores and relays them immediately, checks access on
subscribe and again whenever links or memberships change.
- app/frontend/collab/: the store stays position-based; a binding maps it
to a Yjs form with stable row/column ids, so a row inserted by one
person doesn't misplace what another is typing. Remote changes are
applied only after pending local ones went into Yjs.
- Per-person undo (Y.UndoManager), presence via awareness: the others'
selections as coloured boxes with names, avatars in the toolbar.
- Existing JSON documents convert on first open, deterministically, so
two people opening one at once end up with the same Yjs state.
- Editors compact the stored updates after 200 and keep a JSON snapshot
current for export and duplicating. Edit lock and polling are gone.

The app becomes a Rails 8 application; the Vue frontend moves to
app/frontend and is served through vite_rails.
- Without an account documents stay in the browser (IndexedDB). Sign-in
is by magic link or the 6-digit code from the same mail; afterwards
local documents can be uploaded into the account.
- Server documents (/d/<id>) with versioned saves and a single-editor
lock per browser tab; others see them read-only and follow by polling.
- Sharing via link (works without an account) and via e-mail invitation,
roles viewer/editor; the owner manages links and people.
- Store gains a read-only mode that blocks all content changes.
- Solid Queue, Cache and Cable share the one PostgreSQL database.

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
