Greptile Summary

This PR updates the hero pill in HeroSection.tsx to point to the June 2026 Arena leaderboard blog post, replacing the previous May benchmark link and label.

Confidence Score: 5/5

A two-line content swap — a new blog URL and an updated month label. No logic, state, or component structure is touched.

The change is purely cosmetic: one href and one string literal are updated to reflect the June 2026 Arena leaderboard post. Nothing functional is altered.

No files require special attention.
