Subject: [PATCH] fix(net): hold queued _writev chunks by reference instead of
 concat + native copy

Socket.prototype._writev was concatenating all chunks into one Buffer via
Buffer.concat(), then passing to _write which copies again. For high-throughput
scenarios this pays for three copies of the queue.

Fix: pass chunks array directly to _write which can handle it natively,
avoiding the intermediate Buffer.concat().

Fixes #35940
