Building a Hands-Off Coding Workflow

## Add dark mode toggle to settings

### Context
Users have been requesting dark mode. We already 
have the theme context set up in /providers.

### Requirements
- Toggle switch in settings page
- Persist to localStorage
- Immediate theme switch (no flash)

### Files to look at
- src/providers/theme-provider.tsx
- src/app/settings/page.tsx

### Acceptance Criteria
✓ Toggle visible and functional
✓ Persists across sessions
✓ Matches existing UI patterns

export default {
  async fetch(request: Request, env: Env) {
    const payload = await request.json();
    
    // Verify Linear's webhook signature
    const signature = request.headers.get('linear-signature');
    if (!verifySignature(payload, signature, env.LINEAR_WEBHOOK_SECRET)) {
      return new Response('Invalid signature', { status: 401 });
    }
    
    // Only process when assigned to Claude
    if (payload.data.assignee?.name !== 'Claude Code') {
      return new Response('Ignored');
    }
    
    // Trigger GitHub Actions via repository_dispatch
    await fetch(
      `https://api.github.com/repos/${env.GITHUB_REPO}/dispatches`,
      {
        method: 'POST',
        headers: {
          'Authorization': `Bearer ${env.GITHUB_TOKEN}`,
          'Accept': 'application/vnd.github.v3+json',
        },
        body: JSON.stringify({
          event_type: 'claude-ticket',
          client_payload: {
            ticket_id: payload.data.id,
            title: payload.data.title,
            description: payload.data.description,
            branch: `claude/${payload.data.identifier}`
          }
        })
      }
    );
    
    return new Response('Triggered');
  }
