Agent Browser Verify

# Dev Server Verification with agent-browser

**You MUST verify the dev server with agent-browser after starting it.** Do not assume the page works just because the dev server process started. Many issues (blank pages, hydration errors, missing env vars, broken imports) are only visible in the browser. Run this verification before continuing with any other work:

## Quick Verification Flow

```bash
# 1. Open the dev server
agent-browser open http://localhost:3000
agent-browser wait --load networkidle

# 2. Screenshot for visual check
agent-browser screenshot --annotate

# 3. Check for errors
agent-browser eval 'JSON.stringify(window.__consoleErrors || [])'

# 4. Snapshot interactive elements
agent-browser snapshot -i
```

## Verification Checklist

Run each check and report results:

1. **Page loads** — `agent-browser open` succeeds without timeout
2. **No blank page** — snapshot shows meaningful content (not empty body)
3. **No error overlay** — no Next.js/Vite error overlay detected
4. **Console errors** — evaluate `document.querySelectorAll('[data-nextjs-dialog]')` for error modals
5. **Key elements render** — snapshot `-i` shows expected interactive elements
6. **Navigation works** — if multiple routes exist, verify at least the home route

## Error Detection

```bash
# Check for framework error overlays
