perf(content): ⚡️ reduce archive page size by stripping post body

[Swizzzer]

Problem

The current template-generated archive/index.html seems to include the full post.body for each post. This causes the archive page size to grow significantly as the number of posts increases.

For example, with only 20 posts in my blog, the generated archive page was already 10 MB in size.

Solution

Since displaying the full post.body content is unnecessary on an archive page, I modified the template to exclude it. This change reduces the archive page size dramatically in my blog — from 10 MB to 70 KB — without affecting the page's functionality.

Could you send me a comparison of bundle sizes? I'd like to see actual improvement and verify if it's reproducible.
