Scaffold homelab-monitor: Fastify API + React dashboard + CI

Vertical slice for Phase 1 (v1-dashboard milestone): Proxmox collector,
SQLite storage, local auth, and a dashboard UI showing host/container
status cards. Config-driven collector registry so future data sources
(SSH-based hosts, Zabbix, network discovery) plug in without rewiring.

+# Homelab Monitor
+
+A single dashboard for the health of everything in the homelab (documented in
+[`jhodgkin/homelab`](https://git.jerodrigged.com/jhodgkin/homelab)): Proxmox host + LXC
+CPU/mem/disk/pressure, and — as the backlog fills in — SSH-monitored bare-metal boxes, a LAN
+device inventory, and Zabbix alerts. One login instead of N.
+
+Project status, architecture, and how to resume work: see [`CLAUDE.md`](./CLAUDE.md).
+Roadmap: [Gitea issues](https://git.jerodrigged.com/jhodgkin/homelab-monitor/issues), milestone `v1-dashboard`.
+
+## Local development
+
+```bash
+# terminal 1
+cd apps/api && npm install && cp ../../.env.example ../../.env  # fill in .env first
+npm run dev
+
+# terminal 2
+cd apps/web && npm install && npm run dev
+```
+
+Web dev server proxies `/api` to `localhost:3000` (see `apps/web/vite.config.ts`).
+
+## Production deploy
+
+Runs as Docker Compose on CT122 (`homelab-monitor`, 192.168.1.103):

+cd /opt/homelab-monitor
+git pull
+docker compose up -d --build
