feat(ai_advisory): P0 修 leader lock + inline keyboard + callback handler

統帥 2026-04-19 截圖反饋:
  1. 同一告警 22:44 連推 2 則 (多 Pod 都跑 daily loop)
  2. 純文字無按鈕 (無 feedback 閉環 / AI 只建議不執行)

新增 services/ai_advisory_helpers.py (~240 行):
  - try_acquire_daily_lock(job_name): Redis SETNX key 'aiops:daily_lock:{job}:{date}',
    TTL 25h,fail-open (Redis 掛照推,不阻塞).
  - try_acquire_hourly_lock(job_name): 同上 hourly 版 (coverage_evaluator 用).
  - is_snoozed / set_snooze: Redis key 'aiops:snooze:{type}:{target}' TTL 24h.
  - build_ai_advisory_keyboard: 統一 4 按鈕
      ✅ 已處理 / 😴 忽略 24h / 🔍 查看詳情 / 📋 產 kubectl 指令
    callback_data 格式: 'ai_advisory_{action}:{type}:{id}'
  - handle_ai_advisory_callback: 處理 handled/snooze 兩個 action 寫 aol.output.human_feedback,
    view/produce_cmd 留 P1.

4 個 LLM scanner 改用 helper:
  - capacity_forecaster: daily_lock + snooze check per host + 按鈕
  - compliance_scanner: daily_lock (cron only) + snooze per date + 按鈕
  - coverage_evaluator: hourly_lock + snooze per worst_dimension + 按鈕
  - hermes_rule_quality: daily_lock + snooze per primary rule + 按鈕

telegram_gateway.py:
  handle_callback 加 'ai_advisory_*' 路由 (step 1.85 drift 後)
  新增 _handle_ai_advisory_action 方法:
    解析 payload 'type:id' → 呼叫 handle_ai_advisory_callback
    → answer_callback (Telegram toast 回饋)
    → 返回 dict (info_action=True for view/produce_cmd)

統帥鐵律對齊:
  ✅ 多 Pod 場景只 leader 推 (Redis SETNX 保證冪等)
  ✅ 失敗 fail-open 不阻塞主業務 (Redis 掛仍能運作)
  ✅ aol.output 加 human_feedback 供 AI 學習
  ✅ snooze 避免重複告警 (24h TTL)
  ✅ 原 drift 按鈕 pattern 複用 (non-breaking)

明早 AI 將收到:
  - 單一訊息 (非重複)
  - 含 4 按鈕 (手動 feedback 閉環)
  - snooze 後同主題 24h 不再推

view/produce_cmd P1 留下 session (AI 主動 MCP 蒐證 + LLM 產 kubectl command).

+AI Advisory Helpers — Leader Lock + Snooze + Inline Keyboard (ADR-092 升級)
+=============================================================================
+統帥 2026-04-19 反饋:
+  - 多 Pod 重複推 Telegram (leader 機制缺)
+  - 純文字無按鈕 (feedback 無閉環)
+  - AI 只「建議」不「執行」(view_detail 缺)
+
+本 helper 提供 4 LLM scanner 共用:
+  1. daily_job_leader_lock: Redis SETNX,只 leader Pod 跑 daily job (避免 replica 重複)
+  2. is_snoozed: 檢查是否被 snooze 24h (避免同 host/rule 重複告警)
+  3. build_ai_advisory_keyboard: 統一 4 按鈕 (已處理/忽略 24h/查看詳情/產指令)
+
+callback_data 格式 (與 telegram_gateway 對接):
+  'ai_advisory_{action}:{advisory_type}:{advisory_id}'
+  action: handled / snooze / view / produce_cmd
+  advisory_type: capacity_forecast / compliance_posture / rule_quality / coverage_gap
+  advisory_id: aol.op_id (UUID) or 組合 key (host@date)
