Introduces a vendor build pipeline so all third-party browser assets
(Bootstrap, Bootstrap Icons, Font Awesome, marked, jQuery) are served
from local static files instead of external CDNs.
- Add app/package.json with vendor deps and postinstall/build scripts
- Add app/scripts/copy-vendor.js to copy assets to static/vendor/
- Update base.html.j2 to use url_for('static', ...) for all vendor assets
- Update Dockerfile to install Node.js/npm and run npm install
- Update .gitignore to exclude app/node_modules/ and app/static/vendor/
