feat: Add Adopters page with enterprise case studies and fix project icon display

[dongjiang1989]

Summary

• Add new /adopters page showcasing 10 enterprise customer stories from the Astron Agent ecosystem
• Implement two-row marquee animation with opposite scroll directions (row 1 scrolls left, row 2 scrolls right)
• Fix project icon display: configured icons show without gradient background, unconfigured projects fall back to first-letter display
• Fix i18n rendering in BlogHighlightedPosts and BlogLatestPosts components (HTML tags were rendered as text instead of being parsed)

Changes

Code Review

This pull request introduces a new /adopters page showcasing enterprise customer stories, configures custom project icons, and updates the contributor fetching script to support additional repositories and rate-limit handling. Feedback highlights several critical issues: in fetch-contributors.ts, rate-limiting could overwrite the cache with partial data or block CI/CD runners excessively; in BlogLatestPosts.astro, set:html will not render correctly when passed directly to a custom <Button> component; in Footer.astro, registering keydown listeners on page swaps causes memory leaks under Astro View Transitions; and in adopters.astro, duplicated marquee items lack accessibility attributes, and hardcoded translations should reuse existing keys.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
