Summary: Surfer adds new pricing plans

Why It Matters: Surfer now shows clear pricing for different user needs. This helps people pick the right plan.

What Changed:

• Removed the old homepage content about boosting visibility and customer testimonials.
• Added a new section showing three pricing plans: Essential, Scale, and Enterprise.
• Each plan lists its price, what it includes, and why someone should choose it.
• Added a new "AI Tracker" add-on with its own pricing and details.
• Added a detailed comparison table of features across the Essential, Scale, and Enterprise plans.
• Added a new "Frequently Asked Questions" section about how Surfer works, who uses it, supported languages, upgrades/downgrades, cancellation policy, payment methods, and credit usage.
