Deterministic insight classifier

A rule-based classifier that tags alert insights instantly without waiting for a model generation round-trip.

Most alert insights are now tagged by a deterministic rule engine that runs in milliseconds and produces consistent output for the same input. The classifier buckets each insight into one of five states — healthy, degradation, recovery, anomaly, or change — using anomaly scores, error rates, response-time trends, and recent deployment correlation.

The slower explanation path still kicks in for ambiguous cases, but routine incidents no longer pay that cost.
