Under the hood
Artifact comment auto-react can now be silently withheld by a rule, logged once per artifact.
Before scanning an artifact for comments to auto-react to, a rule-gate check now runs first; if the rule withholds, the scan is skipped for that artifact. The first time this happens for a given artifact, a rule_withheld telemetry event fires, and the flag resets once the rule stops withholding so the event can fire again later if needed.
