Add NVIDIA benchmark reporting flow

Tasks are now started simultaneously when multiple are enqueued (e.g.
Run All). The worker drains all pending tasks at once and launches each
in its own goroutine, waiting via WaitGroup. kmsg watcher updated to
use a shared event window with a reference counter across concurrent tasks.
