New .gitea/workflows/website.yaml: on a push to main or website that
touches website/**, build the Astro site with pnpm and deploy
website/dist to the `relplay` Cloudflare Pages project via wrangler —
--branch selects production (main) vs preview (website). Runs on the
bare ci-public runner (node present; pnpm via corepack). Pin pnpm with
package.json's packageManager for deterministic corepack installs.
Requires repo Actions secrets CLOUDFLARE_API_TOKEN + CLOUDFLARE_ACCOUNT_ID.
