CVE-2026-46739: net\ — Fix

Description

Net::Statsd versions before 0.13 for Perl allow metric injections. The metric names are not checked for newlines, colons or pipes. Metrics generated from untrusted sources could inject additional statsd metrics. The update_stats (used for updating counters) and gauge methods do not check that values are numeric (which would block metric injection).
