ci: Make pack compilation explicit in release workflow

Remplace npm run build:full par 3 étapes séparées et nommées :
- Install dependencies (npm ci)
- Compile compendium packs (npm run pack:compile)
- Build CSS and JavaScript (npm run build)

Les compendiums sont désormais générés à la volée depuis packs-src/
à chaque release, indépendamment de l'état commité de packs/.
