ci: build site before Pages deploy and publish dist (#18)

* ci: deploy built dist assets for pages

Run the build pipeline in the Pages workflow, upload only dist/, and add a .nojekyll marker for deployment.\n\nUpdate build scripts so CSS output names match HTML references, remove the stale about CSS minification step, and copy required static assets into dist/.\n\nRemove the non-functional _headers file used by Netlify-style hosting.

* landing: polish spacing, CTA, and scroll reveal effects

Improve the homepage visual rhythm with a section spacing scale, stronger section transitions, and a clearer hero hierarchy.

Moves the SIMULATE action into the hero, adds micro-interactions and subtle starfield motion, and introduces scroll-triggered reveal animations for section content.

Closes #13.

* chore: remove unrelated UI changes from CI PR

Keep PR #12 focused on the build/deploy pipeline by reverting the accidental index and CSS visual changes from this branch.
