GHSA-6CV4-P8M7-4R25 Forge: ReDoS in forge.http response header and cookie trimming

forge.http trims response header and Set-Cookie values with the regular expression /\s$/, which takes quadratic time on a long run of whitespace followed by another character. A server or on-path attacker can block a forge.http client for minutes with one large response header. Fixed in node-forg...
