matchesRateLimitWording function
Whether text carries a rate-limit/quota wording (the guard set above).
Public so hosts can classify retry notices the ladder announces — the
CLI separates [net] connection lost from [net] rate limited lines
and appends the 429_retry session record for the rate-limit class.
Implementation
bool matchesRateLimitWording(String text) =>
_rateLimitGuardPatterns.any((pattern) => pattern.hasMatch(text));
