Replace polling loop (Collect + Sleep) with proper batch collection: - Block on first request via channel receive - Start 500µs timer for collection window - Accumulate requests until timer fires or batch reaches 32KB - Shutdown handling at all blocking points Design doc §3.2.5: '等待组提交触发（500µs 或 32KB，先到者触发）' Add GroupCommitDelay config field (default 500µs, must be > 0 and < 10ms).
