- feat: make custom metrics tracking generic for plugins
- format custom metrics
Replaces the hardcoded avg_memory logic in stats.rs with a generic custom_metrics field (HashMap<String, f64>). Plugins can now implement the custom_metrics method on EventListener to append tracking data like memory_consumption. Since custom_metrics is only called once at the end of all iterations, there are no allocations in the hot benchmarking loop. Also handles deserialization failures smoothly when encountering benchmark records from older versions.
