Subject: [PATCH] fix(recipe): unescape escaped quotes and backslashes in
 quoted values

The SVS boundary scanners (withoutComments, closingBrace, closingSheet,
valueSemicolon) all treat a backslash inside quotes as an escape, but
parseValue only stripped the outer quote pair and returned the raw inner
text, so \" sequences shipped through verbatim. Unescape the escaped
delimiter quote and the escaped backslash when producing the value,
matching what the scanners already accept.

Fixes #392
