Subject: [PATCH] ci: build the site on every PR

The only workflow here deployed on push to main, so a page that broke the
export was found after it landed rather than on the PR. Runs the same
`npx markline export` the deploy uses, so CI validates exactly what ships.

Verified locally: `npm install && npx markline export` succeeds on main.
