Add execution plan analysis MCP tools to Dashboard and Lite#542
Merged
Conversation
Ports the 5 plan analysis tools from PerformanceStudio to both apps: - analyze_query_plan: Analyze cached plan by query_hash - analyze_procedure_plan: Analyze procedure plan by sql_handle/plan_handle - analyze_query_store_plan: Analyze Query Store plan (fetched on-demand from SQL Server) - analyze_plan_xml: Analyze raw showplan XML directly - get_plan_xml: Retrieve raw showplan XML by query_hash Uses ShowPlanParser + PlanAnalyzer (31 anti-pattern rules) to return structured JSON with warnings, missing indexes, parameters, memory grants, and top operators. Dashboard fetches plans from SQL Server PerformanceMonitor database. Lite fetches from DuckDB cache, with Query Store as on-demand SQL Server fallback. Tested end-to-end on both apps against SQL2022.
