Potential Root Cause: Cloudflare Cache

Even with aggressive cache-busting headers, Cloudflare edge returns HIT status:
```
$ curl -I https://dev.opencode.ai/docs/skills/
cf-cache-status: HIT
cache-control: public, max-age=0, must-revalidate

$ curl -s -H "Cache-Control: no-cache" https://dev.opencode.ai/docs/skills/ | grep "~/."
~/.opencode/skill # Old content, not the deployed version
```

This suggests the deployed content is correct, but Cloudflare is serving stale cached versions.

Possible fixes (not tested):

1. Purge Cloudflare cache for `/docs/*` paths
2. Run `bun sst unlock --stage=production` for production
3. Review cache headers in Astro config
