 * Setup Wizard — First-Run Configuration
 *
 * A 5-step wizard that runs on first activation:
 *   1. Welcome — explain the plugin and benefits
 *   2. Form Detection — auto-detect and select form plugins
 *   3. Settings — email, email frequency
 *   4. Google Ads — optional Google Ads connection prompt
 *   5. Finish — 2-tier plan comparison (Free + Pro) and trial CTA
 *
 * LinkedIn Ads integration — disabled pending relay server setup. Re-enable by uncommenting these lines.
 * (A LinkedIn Ads step previously sat between Google Ads and Finish, making this a 6-step wizard.)
 *
 * The wizard saves all settings on the final step and marks
 * itself as completed so it won't show again (unless re-run).
