Add comprehensive crash logging improvements to help diagnose mass session death events: - Add TypeSessionDeath and TypeMassDeath event types for feed visibility - Log pre-death events before killing sessions (who killed, why) - Add mass death detection in daemon (3+ deaths in 30s triggers alert) - Add macOS crash report check in gt doctor - Support session death events in townlog and feed curator Closes hq-kt1o6 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
