    update to go1.24.8

    update to go1.24.8 This minor release includes 10 security fixes following the security policy: - net/mail: excessive CPU consumption in ParseAddress The ParseAddress function constructed domain-literal address components through repeated string concatenation. When parsing large domain-literal components, this could cause excessive CPU consumption. Thanks to Philippe Antoine (Catena cyber) for reporting this issue. This is CVE-2025-61725 and Go issue https://go.dev/issue/75680. - crypto/x509: quadratic complexity when checking name constraints Due to the design of the name constraint checking algorithm, the processing time of some inputs scales non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary certificate chains. Thanks to Jakub Ciolek for reporting this issue. This is CVE-2025-58187 and Go issue https://go.dev/iss…
