Summary: Slidebean adds AI Pitch Deck Reviewer to navigation

Why It Matters: The competitor is expanding their AI toolset beyond creation into automated feedback. This helps them capture users who already have a draft but need expert-level validation before pitching.

What Changed:

• Added "AI Pitch Deck Reviewer" as a primary link in the top navigation menu.
• Updated all internal website links to remove the "www" prefix from the URL structure.
• Removed social media icons for Twitter, Facebook, and Instagram from the bottom of the page.
