Astro's base option was set to /docs to anticipate the reverse-proxy
URL at checkmate.so/docs. Vercel serves the dist folder at the root,
which made every page 404 because Astro had baked /docs/ into every
internal link and asset URL.
## Changes
- Remove base: "/docs" from astro.config.mjs — site now serves at root
- Update Releases nav link to /releases
- Update README's reverse-proxy snippet to strip the /docs prefix
before forwarding to Vercel
## Final URL behaviour
- Direct: https://<vercel-domain>/ → Introduction
- Direct: https://<vercel-domain>/releases/ → Releases
- Proxy: https://checkmate.so/docs/ → strip /docs → Introduction
- Proxy: https://checkmate.so/docs/releases/ → strip /docs → Releases
