chore(dev): drop --heapsnapshot-near-heap-limit auto-dump

Browse Source 
That flag was added for diagnosing the Ink/perf_hooks leak. Now that the
leak is fixed, leaving it on means a 1GB+ snapshot file gets dumped to
cwd whenever heap pressure hits — noisy and not useful day-to-day.
Inspector flag forwarding is kept for normal --inspect usage.
