Read wait_sum from cgroup cpu.stat and export wait_sum_exter_wait_rate using delta_wait_sum / (delta_wait_sum + delta_cpu_usage). Counter reset is guarded before subtraction. Requires kernel.sched_schedstats=1 for wait_sum in cpu.stat. Testing: - gofmt -w core/metrics/cpu_stat.go - GOFLAGS=-mod=mod go build with AppVersion ldflags - Docker dynamic: huatuo-bamai starts, cpu_stat registered, scrape success=1, no panic Closes ccfos#25 Co-authored-by: Cursor <cursoragent@cursor.com>
