feat(plan-management): implement alert-remediation-plan system v1.3

- 8 new store modules + matcher + initialResponse + aggregation + remediation + AlertStateMonitor + planGenerator

- alert chain auto-integrated after runInspection: freeze snapshot + generate response + real-time agg + auto-start monitor

- AlertAIPanel component + MonitoringDetailPanel expandable alert list

- PlanManagementPage: full page with list/edit/AI generate/templates/commands

+/**
+ * 处置执行引擎（remediationEngine）
+ *
+ * 设计原则（D24）：
+ *   - 不直接 import harness 的 capabilityTools
+ *   - 通过 aiBridge.requestToolCall(alert_id, command_id, params) 让 Catty Agent 在它自己的 session 上下文里执行
+ *   - 凭据、审计、权限全部走 Catty Agent 现有链路
+ *
+ * 执行权限分级（D17）：
+ *   - auto        → AI 自动执行，值班员可随时暂停
+ *   - confirm     → 弹确认框，值班员点允许后执行
+ *   - manual_only → 不调 AI，只展示 checklist，值班员手动完成后勾标记
