feat(m/direct)!: make links case-insensitive

It's not good if our links are case sensitive as different
capitalizations aren't that distinct really. It's still important to
make sure we don't mess up capitalization in the UI or when forwarding
to search engines/etc., though

BREAKING-CHANGE: If you're using links that were made with capitals, those links will stop working
