feat: configure CI/CD with Forgejo Actions

- Add Forgejo workflow for automated build and deploy
- Build creates dist/ from public/ then adds Vue app build
- Configure Vite to build to dist/assets/dist with fixed filenames
- Deploy entire dist/ directory to production via FTP
- Add workflow documentation with FTP setup instructions

The workflow mirrors the GitLab CI approach: dist/ is created during build
and synchronized to production root on every push to main.

+# CI/CD avec Forgejo
+
+## Vue d'ensemble
+
+Le workflow `deploy.yml` automatise le build de l'application Vue et le déploiement sur le serveur de production.
+
+## Workflow
+
+À chaque push sur la branche `main` :
+
+1. **Checkout** : Clone le dépôt
+2. **Setup Node.js** : Installe Node.js 20
+3. **Install dependencies** : Installe les dépendances npm
+4. **Build Vue app** : Compile l'application Vue vers `public/assets/dist/`
+5. **Deploy via FTP** : Synchronise les fichiers vers le serveur de production
+
+## Configuration des secrets
+
+Dans Forgejo, configurez les secrets suivants (Settings > Secrets and Variables > Actions) :
+
+- `USERNAME` : Nom d'utilisateur FTP
+- `PASSWORD` : Mot de passe FTP
+- `PRODUCTION_HOST` : Hôte FTP (format : `ftp://host.example.com`)
+
+## Fichiers déployés
+
+Le workflow déploie depuis le dossier `public/` :
+
+- `public/assets/` → `assets/` (incluant le build Vue dans `assets/dist/`)
+- `public/site/` → `site/` (excluant accounts/, cache/, sessions/)
+- `public/kirby/` → `kirby/`
+- `public/vendor/` → `vendor/`
+- `public/index.php` → `index.php`
+
+## Build local
+
+Pour tester le build localement :
+
+```bash
+npm run build
+```
+
+Les fichiers seront générés dans `public/assets/dist/` (ignorés par git).
