ci: add GitHub Pages landing workflow

[quanbuilds]

Summary

• add a GitHub Pages workflow that builds a static landing page from README.md
• copy the existing assets directory into the published site so README images work
• deploy automatically from main via GitHub Pages, with manual workflow_dispatch support

Notes

• this keeps the repo content source-of-truth in README.md, so the landing page stays current without maintaining a separate docs site
• expected Pages URL after enabling Pages is https://milla-jovovich.github.io/mempalace/

Nice approach — single-source from README.md means the landing page stays in sync automatically. The github-markdown-css stylesheet is a solid choice for rendering quality.

Two quick notes:

• The dark mode CSS only sets background but doesn't switch to github-markdown-dark.min.css. Users on dark OS themes will get dark background + light text styling, which may look off.
• Worth noting this will conflict with #439 (VitePress docs), since both deploy to GitHub Pages. Maintainers may want to pick one approach.
