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
