It's not a "what" question, simply a "where" question.
Put the directory-specific rule before the catch-all rule. This in fact is a basic principle for any redirect or rewrite: order your rules from most specific to most general.
Incidentally, the anchors ^(.*)$ in your rule aren't necessary. They won't do any harm, but they have no effect. By default, Regular Expressions begin capturing as soon as they can and continue as long as they can.
