fix(monitoring): 修復 110 主機 CPU 高負載
CD Pipeline / build-and-deploy (push) Has started running
根因 1: cadvisor 持續掃描 overlay2 磁碟用量 (每次 1-4s × N 容器)
→ 加 --disable_metrics=disk,diskIO,tcp,udp,percpu,sched,process
→ --housekeeping_interval=30s --docker_only=true
→ CPU 從 239% 降到 <1%
根因 2: node_exporter scrape_timeout 預設 10s，高 load 下超時→broken pipe→瘋狂重試
→ 加 scrape_interval: 30s / scrape_timeout: 25s
→ CPU 從 48% 降到 0%
整體 load average: 20 → 9
