feat: use autoimport for components in posts

[taocode]

Blog posts no longer require explicit import of ExternalLink, Link, etc...

Description

It felt weird and redundant to include <script> in the .mds for the ExternalLink and Link components. I love the power of this but would personally prefer to only have to use it for something special, non-standard. Even then, I like the option to configure the imports globally for posts, etc...

Your blog is a great help to me as I deepen my Svelte(+Kit) knowledge. It's fast with advanced image features, plenty for me to learn from. I love how quickly every edit refreshes on the dev side. Thanks for sharing such exemplary code!
