/**
 * Cloudflare Worker — repo request proxy
 *
 * Receives a repo URL from the homepage, creates a GitHub issue
 * (which triggers the auto-add-repo workflow), and returns immediately.
 *
 * Environment secrets (set via wrangler secret put):
 *   GITHUB_TOKEN — fine-grained PAT with issues:write on supermodeltools.github.io
 *
 * Deploy:
 *   cd worker && npx wrangler deploy
 *
 * Route (add in Cloudflare dashboard or wrangler.toml):
 *   repos.supermodeltools.com/api/*  →  this worker
