Summary: ChampSignal adds competitor news and keyword tracking

Why It Matters: This change shows ChampSignal is now tracking more types of competitor activity.

What Changed:

• The website content was completely replaced with a feed of competitor activity alerts.
• The new content shows alerts for "Keywords" and "News" related to competitors like Posthog, Mixpanel, Simple Analytics, Fathom, and Plausible.
• Each alert includes a severity ("High"), a description of the event (e.g., "High search volume and low difficulty for 'trunk based development meaning'", "npm attack compromises libraries linked to PostHog"), and a timestamp.
• The previous marketing and feature description content for ChampSignal was removed.
