Chore: update website

[ricky9667]

This pull request introduces a new static website for the project, replacing the previous Jekyll-based GitHub Pages configuration. It adds a custom index.html landing page styled with Tailwind CSS, updates image assets and demo links in the README.md, and sets up a GitHub Actions workflow to automate deployment to GitHub Pages. The previous remote theme configuration is removed to reflect the new static site approach.

Website overhaul and deployment automation:

• Added a fully custom index.html landing page using Tailwind CSS, featuring sections for introduction, features, community, and support, as well as updated screenshots and demo images.
• Introduced a GitHub Actions workflow (.github/workflows/pages.yml) to automate building and deploying the static site to GitHub Pages on pushes to master or chore/update-website branches.
• Removed the Jekyll remote theme configuration from _config.yml to disable the previous theme and support the new static site.

Documentation and asset updates:

• Updated demo image links in the README.md to match new filenames and reflect the latest UI/feature demos.

assets/demo.gif is used directly on the landing page; in this repo it’s ~22MB, which will significantly slow first load and increase data usage. Consider replacing large GIFs with compressed MP4/WebM (with a poster) and/or adding lazy-loading for below-the-fold media.

The site loads Tailwind from an external CDN (unpkg) without Subresource Integrity. For supply-chain hardening, consider self-hosting the compiled CSS or adding SRI + crossorigin attributes so a compromised CDN response can’t inject arbitrary CSS/JS into the site.
