Summary: ChampSignal adds competitor activity feed

Why It Matters: The website now shows a live feed of competitor news, ads, and keyword changes. This makes the product seem more active and useful.

What Changed:

• The homepage now starts with a list of recent competitor activities for Mixpanel, Posthog, Simple Analytics, Fathom, and Plausible.
• Each activity entry includes the competitor's name, the type of activity (News, Google Ads, Keywords, Reddit, Website), a severity level (High), a short description, and a timestamp.
• The previous homepage content, including navigation, product descriptions, testimonials, pricing, and FAQs, has been removed from the initial view.
