fix: force frontend builder stage to native platform, fixes QEMU arm64 npm crash

Tier 1 — quality.yml: ShellCheck on lxc-install.sh, hadolint on both Dockerfiles
Tier 2 — docker-ci.yml: build images, smoke-test backend health + frontend 200
Tier 3 — test_integration.py: full stack pytest (auth, canvas save/reload, dimensions)
Also adds Docker healthcheck to backend service in docker-compose.yml

+cd homelable && docker compose up -d
+```
+
+Open **http://localhost:3000** — login with `admin` / `admin`.

+> Change the password before exposing to a network: edit `.env` and update `AUTH_USERNAME` / `AUTH_PASSWORD_HASH`.
+>
+> Generate a new hash: `docker compose exec backend python -c "from passlib.context import CryptContext; print(CryptContext(schemes=['bcrypt']).hash('yourpassword'))"`
+>
+> ⚠️ Keep the single quotes around the hash value in `.env` — bcrypt hashes contain `$` characters that Docker Compose would otherwise misinterpret.
+
+## Quick Start — Frontend only
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/install.sh | bash -s -- --standalone
+cd homelable && docker compose up -d
+```
+
+## Update (Docker)
+
+Re-run the install script — it detects an existing install and only updates `docker-compose.yml`:
+

+curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/install.sh | bash
+cd homelable && docker compose pull && docker compose up -d
+```
+
+## Build from source

+cd homelable
+cp .env.example .env
+docker compose up -d

+
+## Proxmox LXC Install
+
+Run this **on the Proxmox host** — it creates a Debian 12 LXC container and installs Homelable inside automatically:
+
+```bash
+bash <(curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/scripts/install-proxmox.sh)

+
+Default container settings: 2 cores, 1 GB RAM, 8 GB disk, DHCP on `vmbr0`. Override before running:
+
+```bash
+CTID=150 RAM=2048 STORAGE=local-zfs bash <(curl -fsSL .../install-proxmox.sh)
+```
+
+The backend runs as a systemd service, the frontend is served via nginx on port 80.
+
+> To install manually inside an existing Debian/Ubuntu machine or LXC:
+> ```bash
+> bash <(curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/scripts/lxc-install.sh)
+> ```
+
+### Update (LXC)
+
+Run the update script inside the container (pulls latest code, rebuilds frontend, restarts services — `.env` and database are never touched):
+
+```bash
+sudo bash /opt/homelable/scripts/update.sh
+```
+
+Or directly from GitHub:
+
+```bash
+sudo bash <(curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/scripts/update.sh)
+```
+
+---
+
+## Configuration
+
+All configuration is done via `.env` (copied from `.env.example`):
+
+```env
+SECRET_KEY=change_me_in_production
+
+# Auth — default: admin / admin
+AUTH_USERNAME=admin

+SCANNER_RANGES=["192.168.1.0/24"]

-## Development Mode
+## MCP Server (AI Integration) (optionnal)
 
-**Backend (Python 3.13):**
-```bash
-cd backend
-python3.13 -m venv .venv && source .venv/bin/activate
-pip install -r requirements.txt
-cp ../.env.example .env       # edit SECRET_KEY and review defaults

+Homelable can exposes a [Model Context Protocol](https://modelcontextprotocol.io) server so any MCP-compatible AI client (Claude Code, Claude Desktop, Open WebUI…) can read your homelab topology and act on it.
+
+### What the AI can do
+
+| | Action |
+|---|---|
+| **Read** | List all nodes, edges, full canvas, pending devices, scan history |
+| **Write** | Add / update / delete nodes and edges, trigger a network scan, approve or hide discovered devices |
+
+### Setup
+
+**1. Add the keys to your `.env`:**
+
+```env
+# Authenticates AI clients (Claude Code, etc.) → MCP server
+MCP_API_KEY=mcp_sk_changeme
+
+# Authenticates MCP server → backend (internal Docker network only, never exposed)
+MCP_SERVICE_KEY=svc_changeme
+
+# Generate both with:
+# python3 -c "import secrets; print(secrets.token_hex(32))"
 ```
 
-**Frontend:**
+No plain-text passwords involved — `AUTH_PASSWORD_HASH` is only used for the web UI login.
+
+**2. Start the MCP service:**
+
 ```bash
-cd frontend
-npm install
-npm run dev   # http://localhost:5173
+docker compose up -d mcp
+# MCP server is now listening on http://<your-homelab-ip>:8001
 ```
 
+**3. Configure your AI client:**
+
+**Claude Code** — run this command in your terminal:
+```bash
+claude mcp add --transport sse homelable http://<your-homelab-ip>:8001/mcp \
+  --header "X-API-Key: mcp_sk_yourkey"
+```
+
+Or add it manually to `~/.claude.json`:
+```json
+{
+  "mcpServers": {
+    "homelable": {
+      "type": "sse",
+      "url": "http://<your-homelab-ip>:8001/mcp",
+      "headers": {
+        "X-API-Key": "mcp_sk_yourkey"
+      }
+    }
+  }
+}
+```
+
+**Claude Desktop** — edit `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `%APPDATA%\Claude\claude_desktop_config.json` (Windows):
+```json
+{
+  "mcpServers": {
+    "homelable": {
+      "type": "sse",
+      "url": "http://<your-homelab-ip>:8001/mcp",
+      "headers": {
+        "X-API-Key": "mcp_sk_yourkey"
+      }
+    }
+  }
+}
+```
+
+### Example prompts
+
+- *"What nodes are currently offline?"*
+- *"Add a new LXC container named `pihole` at 192.168.1.5, connected to my switch."*
+- *"Trigger a network scan on 192.168.1.0/24 and show me the pending devices."*
+- *"Show me the full canvas topology."*
+
+### Security
+
+- The MCP server is **not** intended to be exposed to the internet — keep port 8001 firewalled to your LAN.
+- Rotate the key any time by updating `MCP_API_KEY` in `.env` and restarting: `docker compose restart mcp`.
+- The MCP server communicates with the backend over the internal Docker network — the backend API is never directly exposed to MCP clients.
