chore(cd): deploy b3dc41f [skip ci]

INC-20260507-99ADF2 根因（feedback_full_chain_first_then_fix.md 全鏈分析）：

【鏈路斷點】規則層（5/3 加）vs 指標層（5/6 改）vs scrape 層（從沒同步）
- 577250a6（5/3）「反消音化」commit 加了 FlywheelExecutionRateMissing
  rule，要求 110 Prom scrape 到 awoooi_flywheel_execution_success_rate；
- a2c4b3d4（5/6）Codex 改 FlywheelStatsService 用 auto_repair_executions
  作 source of truth（24h 樣本 1-9 筆回 None 給 W-3b watchdog 接管）；
- 但 awoooi_flywheel_* 指標自始至終只在 /api/v1/stats/flywheel/metrics
  暴露，110 Prom awoooi-api job 抓的是 /metrics → absent() 永遠 1
  → 自 2026-05-06T04:14 UTC 起 firing 26h+ 屬 dead alert

【修法】只動 awoooi-api 一處，不碰 Codex 設計、不碰 110 Prom 配置：
- main.py /metrics endpoint 改 async，在 generate_latest() 後串入
  FlywheelStatsService.compute() → to_prometheus_lines()。
- 既有 awoooi-api scrape job 自動拿到飛輪指標。
- 完全保留 Codex a2c4b3d4 設計：1-9 筆回 None 讓 W-3b watchdog 雙保險。

【不碰的部分】
- flywheel_stats_service.py 不動：Codex 5/6 LOGBOOK 已明確說明
  「Redis playbook counter 失準 → 用 auto_repair_executions 為唯一信任源」，
  1-9 筆 return None 是配合 ai_slo_watchdog_job W-3b grace+30min 設計的
  反消音化雙保險，不是 bug。

驗證計畫（部署後）：
1. curl /metrics | grep awoooi_flywheel  → 看到飛輪指標
2. Prom query awoooi_flywheel_execution_success_rate  → 非空
3. ALERTS{alertname="FlywheelExecutionRateMissing"}  → resolved
4. 30 分鐘觀察 Telegram 不再收 INC-20260507-99ADF2
