Native Windows-Auslieferung statt Container

Docker faellt weg. Das Projekt hat keine npm-Abhaengigkeiten und Node fuehrt
TypeScript direkt aus - der Container schrieb nur noch drei Programme fest,
und dafuer braucht es keine Virtualisierung, sondern einen Ordner.

Der Anlass war, dass ADR-0004 zwar `docker compose pull` versprach, es aber
nie ein veroeffentlichtes Image gab. Wer installieren wollte, musste
whisper.cpp aus dem Quelltext uebersetzen.

Plattformschicht (packages/core/src/platform.ts):
- Programme werden neben der Anwendung gesucht, nicht im PATH
- Daten unter %LOCALAPPDATA%, damit Installation und Update ohne
  Administratorrechte auskommen
- Schriften mitgeliefert: ohne fontsdir setzt libass wortlos eine
  Ersatzschrift ein - gemessen 720 statt 826 Pixel Zeilenbreite

Windows-Eigenheiten, an echtem ffmpeg 8.1 durchprobiert:
- Pfade im Filtergraphen brauchen alle drei Schritte (Vorwaertsschraegstriche,
  escapter Doppelpunkt, Anfuehrungszeichen); je zwei davon reichen nicht
- `nice` gibt es nicht, ersetzt durch os.setPriority

Auslieferung:
- scripts/build-package.ts baut das Paket, laeuft auch unter Linux
- install.ps1 ohne Administratorrechte, Autostart ueber den Aufgabenplaner
- update legt neue Fassungen bereit; eingespielt wird beim naechsten Start,
  nie mitten im Stream
- ZIP lesen und schreiben ohne Abhaengigkeiten (packages/core/src/zip.ts)

Kein `irm ... | iex`-Einzeiler: git.zeasy.dev antwortete instanzweit mit einer
Umleitung auf /user/login, und `iex` fuehrte die Anmeldeseite als PowerShell
aus. Der Updater verfolgt Umleitungen jetzt nicht und hat keine erfundene
Vorgabeadresse mehr.

Ausserdem: backup.ps1 war an zwei Stellen dokumentiert, aber nie geschrieben.

ADR-0007 ersetzt ADR-0004. 84 Tests, Typpruefung sauber.
