Subject: [PATCH] ci: deploy the wasm web app to GitHub Pages on each release
 (issue #45)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add .github/workflows/pages.yml: on every published release (and manual
dispatch) it builds the web bundle with trunk
(`--public-url /OpenCADStudio/`, no-default-features so no solid3d/C
deps), adds .nojekyll, and publishes dist/ to GitHub Pages. No COOP/COEP
needed since wasm runs single-threaded.

Enable via repo Settings → Pages → Source: GitHub Actions.
