The issue you're experiencing seems to be related to the way you're constructing your URLs. In HTML, if you start a URL with a slash (/), it will be relative to the root of your site. If you don't start it with a slash, it will be relative to the current page.
In your case, you're not starting your URLs with a slash, so they're relative to the current page. This is why when you're on mysite.com/docs/introduction and you click on the "features" link, you're taken to mysite.com/docs/introduction/features.
To fix this, you should start your URLs with a slash to make them relative to the root of your site. Here's how you can modify your code:
---
const entries = await getCollection('docs');
---
<a href={`/${entry.slug}`}>{entry.data.title}</a>
This way, when you click on the "features" link, you should be taken to mysite.com/docs/features, regardless of the current page.
Please note that this solution assumes that your entry.slug values are something like docs/introduction and docs/features. If they're just introduction and features, you'll need to add docs/ to the URL in your code:
<a href={`/docs/${entry.slug}`}>{entry.data.title}</a>
