fix(github): authenticate API calls to fix rate-limited star count showing 0

Unauthenticated GitHub API calls are capped at 60 req/hr per IP — easily
exhausted in production. Add optional GITHUB_TOKEN support via Astro's env
schema to raise the limit to 5000/hr.

Also fix the error fallthrough: on non-404 errors the handler logged but
continued, risking stale/zero data; now returns defaultValues immediately.

Add GITHUB_TOKEN as a secret env var in Cloudflare Pages → kestra-io project
→ Settings → Environment variables. Use the value of GH_READ_ORG_TOKEN.
