I really doubt you could find a single regex to do what you want, simply because JS is too complicated a language to parse with a single regex. You could probably do it if you imposed severe restrictions on your coders (no comments on the first line, never put opening curly brace on a line by itself, that kind of thing), in which case you'd also have to do that to every script you get from somewhere else.
My advice would be to construct a parser. You can find a bnf-like grammar for JS 1.4 at mozilla.org. I couldn't spot a JS 2.0 grammar, though that doesn't mean it's not there. ;-) There are also tools to construct parsers in Perl on CPAN, like Parse::YAPP and Parse::RecDescent. It shouldn't be too hard to glue the two together -- probably easier than trying to maintain strict control over 400K of code.
