CVE-2026-89317JwtVerifierImpl.Verify does not enforce the JWS `crit` header (RFC 7515 §4.1.11)

Beschreibung

gose parsed the JWS `crit` header into `JwsHeader.Crit` and then never read it. RFC 7515 §4.1.11 requires a recipient to reject a JWS whose listed critical extension parameters it does not understand. gose implements no header extensions, so every token carrying a non-empty `crit` should have been rejected — and none were.
