docs: add user-facing README and update compose for production

Add README with Docker setup instructions for self-hosting. Update
docker-compose.yml to use the pre-built registry image instead of
local build, and add a healthcheck against /api/health.

 # GearBox
 
+A single-user web app for managing gear collections (bikepacking, sim racing, etc.), tracking weight and price, and planning purchases through research threads.
+
+## Features
+
+- Organize gear into categories with custom icons
+- Track weight and price for every item
+- Create setups (packing lists) from your collection with automatic weight/cost totals
+- Research threads for comparing candidates before buying
+- Image uploads for items and candidates
+
+## Quick Start
+
+### Docker Compose (recommended)
+
+Create a `docker-compose.yml`:
+
+```yaml
+services:
+  gearbox:
+    image: gitea.jeanlucmakiola.de/makiolaj/gearbox:latest
+    container_name: gearbox
+    ports:
+      - "3000:3000"
+    environment:
+      - NODE_ENV=production
+      - DATABASE_PATH=./data/gearbox.db
+    volumes:
+      - gearbox-data:/app/data
+      - gearbox-uploads:/app/uploads
+    healthcheck:
+      test: ["CMD", "bun", "-e", "fetch('http://localhost:3000/api/health').then(r=>r.ok?process.exit(0):process.exit(1)).catch(()=>process.exit(1))"]
+      interval: 30s
+      timeout: 5s
+      start_period: 10s
+      retries: 3
+    restart: unless-stopped
+
+volumes:
+  gearbox-data:
+  gearbox-uploads:
+```
+
+Then run:
+
+```bash
+docker compose up -d
+```
+
+GearBox will be available at `http://localhost:3000`.
+
+### Docker
+
+```bash
+docker run -d \
+  --name gearbox \
+  -p 3000:3000 \
+  -e NODE_ENV=production \
+  -e DATABASE_PATH=./data/gearbox.db \
+  -v gearbox-data:/app/data \
+  -v gearbox-uploads:/app/uploads \
+  --restart unless-stopped \
+  gitea.jeanlucmakiola.de/makiolaj/gearbox:latest
+```
+
+## Data
+
+All data is stored in two Docker volumes:
+
+- **gearbox-data** -- SQLite database
+- **gearbox-uploads** -- uploaded images
+
+Back up these volumes to preserve your data.
+
+## Updating
+
+```bash
+docker compose pull
+docker compose up -d
+```
+
+Database migrations run automatically on startup.
