Add messages block to campaign-generator workflow with professional tone

[Copilot]

The campaign-generator workflow was missing custom message templates under safe-outputs:, causing it to use default messaging instead of campaign-appropriate communication.

Changes

• Added messages: block to .github/workflows/campaign-generator.md under safe-outputs:
  • footer: Campaign coordination attribution with 🎯 emoji
  • run-started: Campaign processing notification
  • run-success: Campaign setup completion message
  • run-failure: Campaign interruption warning
• Recompiled workflow to update .lock.yml with encoded messages

Message style

Messages use professional, clear language for campaign coordination:

messages:
  footer: "> 🎯 *Campaign coordination by [{workflow_name}]({run_url})*"
  run-started: "🚀 Campaign Generator starting! [{workflow_name}]({run_url}) is processing your campaign request for this {event_type}..."
  run-success: "✅ Campaign setup complete! [{workflow_name}]({run_url}) has successfully coordinated your campaign creation. Your project is ready! 📊"
  run-failure: "⚠️ Campaign setup interrupted! [{workflow_name}]({run_url}) {status}. Please check the details and try again..."

This follows the pattern used in other workflows (e.g., craft.md, dev-hawk.md, breaking-change-checker.md) but with campaign-specific messaging instead of themed variations.

Original prompt

In campaign generator, add a messages: block under safe-outputs: in .github/workflows/campaign-generator.md, similar to how smoke-codex.md does it, so it does not talk like a pirate but in a normal tone and messages that fit for campaigns.
