feat(adr-082): Phase 2 多 Agent 協作 — 5 角色辯證系統骨架上線
新增 5 個 Agent + Orchestrator + DecisionManager 接線：
- protocol.py: DiagnosisReport / ActionPlan / ReviewVerdict / CriticReport / DecisionPackage 型別系統
- DiagnosticianAgent: RCA 根因分析，confidence < 0.4 → ABSTAIN
- SolverAgent: 修復方案軍師，blast_radius 評分 + 降級 rule-based mock
- ReviewerAgent: 安全審查，HARD_RULES 靜態 pattern + blast_radius 閾值 (>50 revision, >80 reject)
- CriticAgent: 刻意唱反調，強制 3 問批判性思維，critical challenge → REJECT
- CoordinatorAgent: 純規則聚合，6 級決策閘，REQUEST_REVISION → 強制人工
- AgentOrchestrator: 30s 全局超時，Reviewer ‖ Critic 並行，DB Immutable Event Sourcing + Redis Streams
- DecisionManager: AIOPS_P2_ENABLED gate + _package_to_proposal_data 橋接既有 proposal_data 格式
- AgentSession DB table + 4 個複合 index
- ADR-082 決策記錄
Gate 2 修復（7 項）:
- CRITICAL: DELETE FROM regex lookahead 位置錯誤（移至 FROM 後）
- CRITICAL: REQUEST_REVISION 可抵達 auto-execute 路徑（改回 requires_human_approval=True）
- IMPORTANT: _extract_json flat regex 不支援巢狀 JSON（改 find/rfind 邊界提取）
- IMPORTANT: all_degraded 遺漏 verdict.degraded（補全 4 個 Agent）
- IMPORTANT: Solver ABSTAIN guard 放行降級假設（改為無論 hypotheses 有無均跳過）
- IMPORTANT: dataclasses.asdict() Enum 未序列化導致 DB 寫入靜默失敗（加 json.dumps default handler）
- IMPORTANT: P2 gate 直讀屬性繞過父 Phase 守衛（改用 is_phase_enabled(2)）
