When "find" is a string, the replacement was passed directly as the second argument of String.replace, so special replacement patterns were expanded: a replacement of "$$" produced a single "$", "$&" inserted the matched substring, etc.

[Medium risk] Fixes string alias replacement to handle special characters.

This PR appears safe to merge.

What we checked:

• RegExp replacements still work: Only string matches use the new callback. RegExp matches still pass the replacement string directly to replace.
