fix(arch-review): 首席架構師審查 S1×3 S2×3 S3×3 全修復 + ADR-064
Some checks failed
CD Pipeline / build-and-deploy (push) Has been cancelled

S1 Critical:
- S1-1: asyncio 觸發移至 _call_with_fallback async 上下文,移除 sync 中的 get_event_loop()
- S1-2: _append_rule_to_yaml 加 textwrap.dedent() 正規化 LLM 輸出縮排
- S1-3: _matches() 對 alertname=["*"] 直接回傳 False,防意外命中

S2 Major:
- S2-1: auto_generate_rule() 改為 DI 參數注入 (ollama_url/model/gemini_api_key),移除 import settings
- S2-4: _generate_mock_response docstring 澄清為規則引擎生產路徑,非假數據
- S2-5: suggested_action .strip() 防空白字串繞過 or

S3 Minor:
- S3-2: priority 上界 min(next, 890)
- S3-3: alertname sanitize re.sub([{}]) 防 format KeyError
- S3-4: model_registry.py 最後修改時間戳更新

文件:
- ADR-064: Alert Rule Engine YAML 驅動 + AI 自動學習
- Skills 02: 告警規則引擎 DI 規範 + asyncio 禁止事項
- Skills 03: _generate_mock_response 語意澄清 + 規則引擎降級流程
- LOGBOOK: 本次 Session 完整記錄
