Perf: Optimiser builds backend avec image de base (90-95% plus rapide)

Architecture en 2 images: - Image base (audio-classifier-base): deps système + Python (~15min, 1x/semaine) - Image app (audio-classifier-backend): code uniquement (~30s-2min, chaque commit) Fichiers ajoutés: - backend/Dockerfile.base: Image de base avec toutes les dépendances - .gitea/workflows/docker-base.yml: CI pour build de l'image de base - backend/DOCKER_BUILD.md: Documentation complète Fichiers modifiés: - backend/Dockerfile: Utilise l'image de base (FROM audio-classifier-base) - .gitea/workflows/docker.yml: Passe BASE_IMAGE en build-arg Gains de performance: - Build normal: 15-25min → 30s-2min (90-95% plus rapide) - Trigger auto du build base: quand requirements.txt change - Trigger manuel: via interface Gitea Actions 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

+# Docker Build Optimization
+
+Cette configuration utilise une approche en 2 images pour accélérer les builds backend de **15-25 minutes** à **30 secondes - 2 minutes**.
+
+## Architecture
+
+### Image 1 : Base (`audio-classifier-base`)
+Contient toutes les dépendances système et Python qui changent rarement :
+- Python 3.9 + apt packages (ffmpeg, libsndfile, etc.)
+- numpy, scipy, essentia-tensorflow
+- Toutes les dépendances de `requirements.txt`
+
+**Build** : ~15 minutes (1 fois par semaine ou quand `requirements.txt` change)
+
+### Image 2 : App (`audio-classifier-backend`)
+Hérite de l'image de base et ajoute uniquement le code applicatif :
+- Code source (`src/`)
+- Fichiers de configuration (`alembic.ini`)
+- Modèles Essentia (`models/`)
+
+**Build** : ~30 secondes - 2 minutes (à chaque commit)
+
+## Workflows CI/CD
+
+### 1. Build de l'image de base (`.gitea/workflows/docker-base.yml`)
+Se déclenche automatiquement quand :
+- `backend/requirements.txt` est modifié
+- `backend/Dockerfile.base` est modifié
+- Déclenchement manuel via l'interface Gitea
+
+```bash
+# Image produite :
+git.benoitsz.com/benoit/audio-classifier-base:latest
+git.benoitsz.com/benoit/audio-classifier-base:sha-<commit>
+```
+
+### 2. Build de l'image app (`.gitea/workflows/docker.yml`)
+Se déclenche à chaque push sur `main` :
+- Utilise l'image de base comme FROM
+- Copie uniquement le code source
+- Build rapide (~30s-2min)
+
+```bash
+# Image produite :
+git.benoitsz.com/benoit/audio-classifier-backend:dev
+git.benoitsz.com/benoit/audio-classifier-backend:dev-<commit>
+```
+
+## Utilisation en local
+
+### Build de l'image de base
+```bash
+cd backend
+docker build -f Dockerfile.base -t audio-classifier-base:local .
+```
+
+### Build de l'image app (utilise l'image de base)
+```bash
+# Depuis la racine du projet
+docker build \
+  --build-arg BASE_IMAGE=audio-classifier-base:local \
+  -f backend/Dockerfile \
+  -t audio-classifier-backend:local \
+  .
+```
+
+### Build direct (sans image de base) - pour tests
+Si tu veux tester un build complet sans dépendre de l'image de base :
+```bash
+# Revenir temporairement au Dockerfile original
+git show HEAD~1:backend/Dockerfile > backend/Dockerfile.monolithic
+docker build -f backend/Dockerfile.monolithic -t audio-classifier-backend:monolithic .
+```
+
+## Mise à jour des dépendances
+
+Quand tu modifies `requirements.txt` :
+
+1. **Push les changements sur `main`**
+   ```bash
+   git add backend/requirements.txt
+   git commit -m "Update dependencies"
+   git push
+   ```
+
+2. **Le workflow `docker-base.yml` se déclenche automatiquement**
+   - Build de la nouvelle image de base (~15 min)
+   - Push vers `git.benoitsz.com/benoit/audio-classifier-base:latest`
+
+3. **Les prochains builds backend utiliseront la nouvelle base**
+   - Builds futurs rapides (~30s-2min)
+
+## Déclenchement manuel
+
+Pour rebuild l'image de base manuellement (sans modifier `requirements.txt`) :
+
+1. Va sur Gitea : `https://git.benoitsz.com/benoit/audio-classifier/actions`
+2. Sélectionne le workflow "Build Base Docker Image"
+3. Clique sur "Run workflow"
+
+## Monitoring
+
+Vérifie les builds dans Gitea Actions :
+- **Base image** : `.gitea/workflows/docker-base.yml`
+- **App image** : `.gitea/workflows/docker.yml`
+
+Les logs montrent la durée de build pour chaque étape.
+
+## Gains de performance attendus
+
+| Scénario | Avant | Après | Gain |
+|----------|-------|-------|------|
+| Build normal (code change) | 15-25 min | 30s-2min | **90-95%** |
+| Build après update deps | 15-25 min | 15-25 min (base) + 30s-2min (app) | 0% (1ère fois) |
+| Builds suivants | 15-25 min | 30s-2min | **90-95%** |
+
+## Troubleshooting
+
+### Erreur "base image not found"
+L'image de base n'existe pas encore dans le registry. Solutions :
+1. Trigger le workflow `docker-base.yml` manuellement
+2. Ou build localement et push :
+   ```bash
+   docker build -f backend/Dockerfile.base -t git.benoitsz.com/benoit/audio-classifier-base:latest backend/
+   docker push git.benoitsz.com/benoit/audio-classifier-base:latest
+   ```
+
+### Build app lent malgré l'image de base
+Vérifie que le build-arg `BASE_IMAGE` est bien passé :
+```yaml
+build-args: |
+  BASE_IMAGE=${{ env.REGISTRY }}/${{ gitea.repository_owner }}/audio-classifier-base:latest
+```
+
+### Dépendances Python pas à jour dans l'app
+L'image de base doit être rebuildée. Trigger `docker-base.yml`.
