[plan] Add 'Getting Started with Claude' example to engines.md

[github-actions]

Context

As identified in discussion #12027, the engines documentation lacks a complete quick-start example for Claude users. While Claude setup instructions exist, there's no end-to-end "hello world" workflow to demonstrate the complete experience.

Problem

• Claude users need to piece together information from multiple sections
• No single example showing: frontmatter + workflow code + authentication setup
• Missing a "success path" that users can copy-paste and run immediately
• Documentation shows detailed explanations but lacks practical quick-start

Objective

Add a complete, minimal Claude workflow example that users can copy-paste and run successfully within minutes.

Proposed Solution

Add after the Claude Setup section in docs/src/content/docs/reference/engines.md:

### Quick Example: Issue Triage with Claude

Here's a complete example to get started with Claude:

**1. Create `.github/workflows/issue-triage.md`:**

```markdown
---
engine: claude
on: issues
permissions:
  contents: read
  issues: write
safe-outputs:
  add-comment:
---

# Issue Triage

Analyze this issue and provide helpful triage suggestions:

1. Identify the issue type (bug, feature request, question, etc.)
2. Check if the issue has enough information
3. Suggest appropriate labels
4. Provide a helpful response
```

**2. Set up your Anthropic API key:**

```bash
gh aw secrets set ANTHROPIC_API_KEY --value "sk-ant-..."
```

**3. Compile and push the workflow:**

```bash
gh aw compile .github/workflows/issue-triage.md
git add .github/workflows/issue-triage.lock.yml
git commit -m "Add Claude-powered issue triage workflow"
git push
```

**4. Test it:** Open a new issue in your repository - Claude will automatically analyze and comment!

Files to Modify

• docs/src/content/docs/reference/engines.md (add after Claude Setup section, around line 77)

Acceptance Criteria

• Add complete quick-start example with all steps
• Include frontmatter configuration
• Include workflow markdown content
• Include authentication setup command
• Include compilation and deployment steps
• Include testing instructions
• Verify example is copy-pasteable and works as-is
• Example should be runnable within 5 minutes

Testing

Verify the example works:

1. Follow the steps exactly as written
2. Ensure the workflow compiles without errors
3. Ensure the workflow triggers on a test issue
4. Ensure Claude processes and responds successfully
