Broken relative file links in directory listing

[DeltaF1]

When accessing a URL such as hyper://94f0cab7f60fcc2a711df11c85db5e0594d11e8a3efd04a06f46a3c34d03c418/posts and omitting the trailing slash, the browser does not append a trailing slash, and so relative links on the page don't function as intended.

Steps to reproduce

• Access a URL to a directory with files in a hyperdrive/dat archive and omit the trailing slash
• Click one of the links to a file in the directory

Expected behaviour

• The filename is appended to the URL with a slash in between and the user navigates to the file

Actual behaviour

• The browser does not append the trailing slash to the URL in the navbar, and the link becomes relative to one layer higher than intended

This should maybe be moved to dat-fetch so that dat-fetch can return a 302 and redirect to the canonical version with the trailing '/' if it is a directory.

I'll re-open on dat-fetch when I have a better idea of how I would want this to work. Maybe the directory listing page in agregore should just create links relative to the root rather than relative to ..
