[stannesi] make cloudflare pages build explicit

[stannesi]

Summary

• add explicit root scripts for Cloudflare production and GitHub Pages staging builds
• add root wrangler.toml with the Cloudflare Pages output directory
• update the GitHub Pages workflow to call the GitHub Pages-specific build script
• document exact Cloudflare Pages settings: repo root, pnpm viewer:demo:build:cloudflare, output apps/prd-viewer-web/dist

Notes

The pasted Cloudflare log stopped after dependency install, so the exact failing command line was not visible. This removes the likely ambiguity between Cloudflare project root, build command, base path, and output directory.

Validation

• PATH="/opt/homebrew/bin:$PATH" pnpm viewer:demo:build:cloudflare
• PATH="/opt/homebrew/bin:$PATH" pnpm viewer:demo:build:github-pages
• PATH="/opt/homebrew/bin:$PATH" pnpm docs:check -- --include-root-docs
• git diff --check
• PATH="/opt/homebrew/bin:$PATH" pnpm foundation:gate
