Fix bugs and implement Authentik SSO login

- frontmatter: replace custom YAML parser with gray-matter; add private field (was silently dropped on save)
- types: add private? to NoteMeta so the field propagates through NoteContent
- use-notes: fix all subtopic traversal bugs (deleteNote, renameNote, toggleDraft, updateActiveNote, loadNotes first-select) using recursive mapTopicNotes/filterTopicTree helpers
- api: remove unused moveNote duplicate (moveNoteApi is the correct export)
- auth: add setPendingServerUrl/getPendingServerUrl/clearPendingServerUrl for Authentik redirect flow
- login: implement Authentik SSO flow — save server URL, redirect to /api/studio/auth/authentik, detect #token= on return; show/hide token vs Authentik sections based on server config
- preview: fix useRef type error (missing undefined initializer)

-# noz-studio — Projektübersicht für Claude
-
-> **Kommunikation:** Deutsch. Alle Konversationen, Commit-Messages, Kommentare und UI-Labels auf Deutsch.
-
-## Was ist noz-studio?
-
-noz-studio ist der Web-Editor für [noz](../noz) — ein vollständiger Markdown-Editor als PWA, optimiert für Desktop und Mobile (Touch). Gedacht für Situationen wo noz-cli nicht verfügbar ist (Arbeit, unterwegs, fremdes Gerät).
-
-**noz-studio ist ein Client.** Es schreibt keinen eigenen Content-Store — es spricht ausschließlich gegen die noz-API. Die einzige Verbindung zwischen noz und noz-studio sind API-Endpunkte.
-
-```
-noz (Server + API)  ←──────────────────────────
-        ↑                  ↑              ↑
-    noz-cli            noz (public)   noz-studio
-   (Terminal)          (Leser)        (Web-Editor)
-```
-
----
-
-## Stack
-
-- **Next.js** (App Router) — gleicher Stack wie noz
-- **CodeMirror 6** — Editor-Engine (MIT-Lizenz) — NUR als Engine, alles außen rum ist custom
-- **Tailwind CSS v4** — OKLCH-Farben, gleiche Palette wie noz aber eigene Design-Sprache
-- **PWA** — `manifest.json` + Service Worker — installierbar auf iOS/Android/Desktop
-
----
-
-## Design-Prinzipien
-
-- **iA Writer-Feel** — fokussiert, clean, Typografie im Vordergrund
-- **Affine-like** — immer offen, kein "speichern"-Stress
-- **Kein localStorage für Credentials** — Token in `sessionStorage` (Tab zu → Token weg, kein Datenleak auf Arbeitsrechnern)
-- **noosphere.toml als Single Source of Truth** — Studio liest Config vom Server, nie hardcoden
-- **CM6 ist swappable** — EditorEngine-Interface abstrahiert die Implementierung
-
----
-
-## Auth-System
-
-Konfiguriert in `noosphere.toml` des noz-Servers:
-
-```toml
-[studio]
-auth         = "token"      # "token" | "authentik" | "both"
-allow_delete = true
-allow_push   = true
-allow_rebuild = false
-```
-
-Studio macht beim Start einen **public Request ohne Token**:
-```
-GET /api/studio/config  →  { auth: "token" | "authentik" | "both", name: "...", lang: "..." }
-```
-Daraufhin zeigt der Login-Screen die passende UI (Token-Formular, Authentik-SSO-Button, oder beides).
-
-**Token-Handling:**
-- Gespeichert in `sessionStorage` — nie `localStorage`
-- Tab schließen = Token weg = kein Datenleak auf fremden Geräten
-- Gleicher Token wie `[cli]` in `noosphere.toml`
-
----
-
-## Draft-System (3 Stufen)
-
-```
-[ Draft ]  →  [ In Review ]  →  [ Live ]
-```
-
-| Stufe | Speicherort | Sichtbar auf noz? | Wer sieht es? |
-|-------|-------------|-------------------|---------------|
-| **Draft** | `content/noosphere/_drafts/notiz.md` | Nein (Index-Builder überspringt `_`-Ordner) | Nur Studio |
-| **In Review** | `content/noosphere/topic/notiz.md` + `draft: true` im Frontmatter | Nur via Authentik/Vault | Eingeloggte User |
-| **Live** | `content/noosphere/topic/notiz.md` (kein draft-Flag) | Ja, öffentlich | Alle |
-
-Der **Draft-Button** im Editor-StatusBar toggelt zwischen den Stufen. Studio kümmert sich um:
-- Datei verschieben (`_drafts/` → topic-Ordner)
-- Frontmatter `draft: true/false` setzen
-- Index-Rebuild triggern (wenn `allow_rebuild = true`)
-
----
-
-## EditorEngine-Interface (CM6 swappable)
-
-```typescript
-// src/components/editor/engine.ts
-interface EditorEngine {
-  getValue(): string
-  setValue(content: string): void
-  onSave(callback: (value: string) => void): void
-  focus(): void
-  destroy(): void
-}
-```
-
-```typescript
-// src/components/editor/cm6-adapter.ts
-class CM6Adapter implements EditorEngine { ... }
-```
-
-```tsx
-// src/components/editor/editor-wrapper.tsx
-// Kennt nur EditorEngine, nie direkt CM6
-```
-
-Wenn CM6 irgendwann getauscht wird → nur `cm6-adapter.ts` anfassen.

-## Verbindung zu noz
-
-noz-studio braucht neue API-Routen in noz (noch nicht gebaut — werden nach dem Studio-Design spezifiziert):
-
-```
-GET    /api/studio/config              # public — Auth-Methode + Site-Config
-GET    /api/cli/notes                  # alle Notes (meta)
-GET    /api/cli/notes/:slug            # Raw Markdown
-POST   /api/cli/notes                  # neue Note — { slug, title, topic, status, lang, content }
-PUT    /api/cli/notes/:slug            # Note aktualisieren
-DELETE /api/cli/notes/:slug            # Note löschen
-POST   /api/cli/notes/:slug/rename     # umbenennen — { newTitle } — Server rewritet Wikilinks
-POST   /api/cli/notes/:slug/move       # Note verschieben — { newTopic } — Server rewritet Wikilinks
-GET    /api/cli/templates              # Templates
-POST   /api/cli/rebuild                # build:index triggern
-
-POST   /api/cli/folders                # Neuer Ordner — { slug, parent? } — legt _index.md an
-PUT    /api/cli/folders/:slug          # Ordner umbenennen — { newSlug } — Server rewritet ALLE internen Links
-DELETE /api/cli/folders/:slug          # Ordner löschen (nur wenn leer — sonst 409)
-```
-
-Alle außer `/api/studio/config` erfordern `Authorization: Bearer <token>`.
-
-### Link-Rewriting beim Verschieben/Umbenennen (Serverseite)
-
-Wenn eine Note verschoben wird (`/move`) oder ein Ordner umbenannt wird (`PUT /folders`):
-1. Datei/Verzeichnis physisch verschieben
-2. In **allen** `.md`-Dateien des Content-Stores Wikilinks ersetzen:
-   - Note-Move: `[[alter-topic/note-slug]]` → `[[neuer-topic/note-slug]]`
-   - Folder-Rename: `[[alter-ordner/...]]` → `[[neuer-ordner/...]]`
-3. Index-Rebuild triggern (wenn `allow_rebuild = true`)
-
-Kurzform: `[[slug]]` ohne Topic-Prefix bleibt unverändert — nur vollqualifizierte Slugs werden rewritten.
-
----
-
-## Design-System
-
-Gleiche OKLCH-Palette wie noz (`globals.css`), aber eigene Layout-Sprache:
-- **Dark by default** (Editor-Feeling)
-- **Newsreader** für Headings (italic), **Inter** für UI, **JetBrains Mono** im Editor
-- Kein Prose-Layout — Editor ist das Zentrum
-
-**Layouts:**
-- Desktop: `[Sidebar 260px] [Editor flex] [Preview flex]`
-- Mobile: Bottom-Nav + Fullscreen-Editor + Swipe zwischen Editor/Preview

+# noz-studio
+
+A web editor PWA for [noz](https://github.com/noz-lab/noz) — write and manage notes from any device, even without the CLI.
+
+> **Personal use.** Built as part of my own noz setup — open source, but things change without notice.
+
+## Features
+
+- **CodeMirror 6** editor with Markdown syntax highlighting
+- **Live preview** — rendered note side by side with the editor
+- **Wikilinks** — `[[Note Title]]` autocomplete and resolution
+- **Diagram canvas** — visual editor for `_diagram.toml` folder diagrams
+- **Full-text search** — search your garden from the sidebar
+- **PWA** — installable, works offline for reading cached notes
+- **Dark / light mode**
+- **Multilingual** (de / en)
+
+## Setup
+
+noz-studio connects to a running noz instance via the CLI API. You need a token configured in your noz server's `.env.local`:
+
+```
+NOZ_CLI_TOKEN=your-secret-token
+```
+
+And in `noosphere.toml`:
+
+```toml
+[studio]
+auth       = "token"   # or "authentik" or "both"
+allow_push = true
+```
+
+Then set the allowed origin for CORS in `.env.local` on your noz server:
+
+```
+NOZ_STUDIO_ORIGIN=https://studio.your-domain.com
+```
+
+## Running locally
+
+```bash
+pnpm install
+pnpm dev   # starts on port 3001
+```
+
+Open `http://localhost:3001`, enter your noz server URL and token.
+
+For local development, you can prefill credentials via environment variables:
+
+```
+NEXT_PUBLIC_DEV_SERVER=http://localhost:3000
+NEXT_PUBLIC_DEV_TOKEN=your-token
+```
+
+## Deployment
+
+noz-studio is a standard Next.js app — deploy anywhere Next.js runs (Vercel, Docker, self-hosted).
+
+The `infra/` folder in [noz](https://github.com/noz-lab/noz) contains a Traefik config for self-hosting behind a reverse proxy.
