proposal: redirect user.tngl.sh/repo to repository page #98

We are already redirecting tangled.org/core to tangled.org/tangled.org/core. Let's expand this further and make it as default behavior for *.tngl.sh user handles.

Similar to how *.bsky.social redirects to bsky.app/profile/*.bsky.social.

Now all users using tangled PDS can have shorter go package name like tangled.org/core.

import "alice.tngl.sh/cool-pkg/foo/bar"

1. more users using tangled PDS
2. atproto gets more decentralized
3. more users try atproto as a next gen open web
4. more tangled users
