Using the root path /: directly in an OAS spec, results in the generator registering it with the literal "/" which is wrong.

It should instead be "/{$}"

This is because, the go http.ServeMux is interpreting trailing / as a wildcard match.

This means that:

• / matches anything
• /cake/ matches anything starting with /cake

The result is that you won't be able to add another handler for all unmatched requests and that the handler for /: will match any unmatched path

The Current Workaround, I'm using for this, is: /\x7B$\x7D: as the root path in my OAS spec.
go will convert these correctly at comp time.
