fix(deploy): publish dist on Cloudflare Pages

Pages was serving the source index.html (referencing /src/main.tsx) because
wrangler.toml lacked pages_build_output_dir, so Pages published the repo root
instead of the Vite build output. Set pages_build_output_dir=dist and restore
the SPA fallback _redirects.
