fix(smart v0.1.11): utiliser /dev/nvme0n1 au lieu de /dev/nvme0

/dev/nvme0  (contrôleur char device) : crw------- root root → root only
/dev/nvme0n1 (namespace block device): brw-rw---- root disk → groupe disk OK

L'agent tourne avec DynamicUser+SupplementaryGroups=disk → a accès au
block device nvme0n1 mais pas au char device nvme0. Les 3 versions
précédentes (v0.1.8-v0.1.10) tentaient toutes d'ouvrir le contrôleur.

+# Améliorations Nanometrics — Plan d'implémentation
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Ajouter métriques réseau enrichies, hardware, config bidirectionnelle, API REST complète, taille police globale.
+
+**Architecture:**
+- Métriques lentes (réseau, hardware) : collecte au démarrage + une fois/jour à heure fixe (config `slow_daily_time`)
+- Stockage dans la table `agents` (colonnes JSON), pas dans `metrics` — ces données changent rarement
+- API REST expose tout via les mêmes endpoints enrichis
+
+**Tech Stack:** Rust (agent), Go (server), SQLite, Vanilla JS (dashboard)
+

+- [ ] **Dans `server/main.go`** — ajouter la route dans le switch `/api/agents/` :

+    handlers.AgentDetailHandler(database)(w, r)
+```
+
+- [ ] **Dans `server/docker-compose.yml`** — ajouter le service iperf3 :
+
+```yaml
+  iperf3:
+    image: ${IPERF3_IMAGE:-public.ecr.aws/docker/library/networkstatic/iperf3:latest}
+    pull_policy: if_not_present
+    restart: unless-stopped

+    ports:

+```
+
+- [ ] **Vérifier** : `cd server && go build ./...`
+
+- [ ] **Commit** :
+```bash

+## Task 7 — Dashboard : section réseau dans popup détail
+
+**Files:**
+- Modify: `dashboard/js/popups.js`
+- Modify: `dashboard/css/app.css`
+
+- [ ] **Ajouter CSS** dans `app.css` pour la section réseau :
+
+```css
+.net-table{display:flex;flex-direction:column;gap:4px}
+.net-row{display:grid;grid-template-columns:auto 1fr 80px 120px 60px 90px;
+         align-items:center;gap:8px;padding:6px 10px;
+         background:var(--bg-3);border-radius:6px;border:1px solid var(--border-1);
+         font-family:var(--font-terminal);font-size:10px}
+.net-row:first-child{background:var(--bg-4);font-size:9px;color:var(--ink-4);letter-spacing:.06em}
+.net-val{font-family:var(--font-mono);font-size:11px;color:var(--ink-2)}
+.hw-grid{display:grid;grid-template-columns:1fr 1fr;gap:6px}
+```
+
+- [ ] **Dans `popups.js`**, après la section STOCKAGE dans `pop-body`, ajouter les sections réseau et hardware. Construire les variables HTML :
+
+```javascript
+const netSection = entry?.agent?.network_info?.length > 0
+    ? /* tableau des interfaces */ ...
+    : '';
+
+const hwSection = entry?.agent?.hardware_info
+    ? /* grille hardware */ ...
+    : '';
+```
+
+Insérer `${netSection}${hwSection}` avant la section INFORMATIONS.
+
+- [ ] **Commit** :
+```bash
+git add dashboard/js/popups.js dashboard/css/app.css
+git commit -m "feat(dashboard): sections réseau et hardware dans popup détail"
+```
+
+---
+
+## Task 8 — Dashboard : font-size global
+
+**Files:**
+- Modify: `dashboard/js/app.js`
+- Modify: `dashboard/css/app.css`
+
+- [ ] **Dans `app.js`**, changer l'application du font-size : appliquer sur `html` (root) au lieu de `body` :
+
+```javascript
+if (_serverConfig.font_size) {
+    document.documentElement.style.fontSize = _serverConfig.font_size + 'px';
+}
+```
+
+- [ ] **Dans `app.css`**, vérifier que les éléments clés utilisent `rem` pour les tailles de police principales. Ajouter la règle de base sur `html` :
+
+```css
+html { font-size: 13px; } /* valeur par défaut, écrasée par JS */
+```
+
+Les éléments qui utilisent déjà des tailles en `px` absolues seront progressivement mis à l'échelle via ce mécanisme. Ceux qui héritent (`font-size: inherit`) bénéficieront automatiquement.
+
+- [ ] **Commit** :
+```bash
+git add dashboard/js/app.js dashboard/css/app.css
+git commit -m "fix(dashboard): font-size global appliqué sur html root"
+```
+
+---
+
+## Task 9 — Release et déploiement
+
+- [ ] **Rebuild agent** : `cargo build --release --manifest-path agent/Cargo.toml`
+- [ ] **Copier binaires** dans `dist/`
+- [ ] **Rebuild Docker** : `cd server && docker compose up -d --build`
+- [ ] **Redéployer l'agent** via `install.sh` sur chaque VM cible
+- [ ] **Push final** : `git push`
