Better search visibility across marketing pages

• SEO overhaul across marketing pages Added social sharing metadata, structured data, and canonical URLs across the homepage, pricing, about, use cases, products, roles, and landing pages so they surface better in search and link previews.
• Cleaner page titles and descriptions Removed duplicate brand names, rewrote use-case titles to be keyword-targeted, and trimmed long titles and descriptions to fit search result limits.
• About page heading hierarchy Cleaned up the page heading structure for better readability and SEO.
• Renamed the blog from "Your AI Customer Compass" to "AI Customer Research Blog" for better discoverability.

Automation errors now display readable messages instead of empty objects.
