Your Name 7cd53c0228 fix(monitoring): 記憶體告警改用 working_set，停止 page cache 假告警

- alerts-unified.yml:
  - SentryClickHouseMemoryPressure: usage_bytes → working_set_bytes，0.8 → 0.85
  - GiteaMemoryPressure: 同步修正（同樣 page cache 虛高根因）
- ops/monitoring/tests/clickhouse_memory_test.yml: promtool 4 cases
- 04-awoooi-devops-commander.md v2.8: Prometheus 指標選擇規範 + Gitea HMAC Webhook 規範
- LOGBOOK: 記錄 T0 五大並行任務（A 按鈕 / B ClickHouse / C Gitea webhook / D ElephantAlpha / F Code review）

鐵證: 2026-04-23 23:13 sentry-clickhouse usage_bytes=88.5% vs working_set=7.8%
根因: container_memory_usage_bytes 含 OS page cache，OOM killer 不視為壓力
修法: 改用 K8s/cadvisor 認可的 working_set_bytes (RSS + active cache)，閾值 0.85
