• src/tools/diagnostics.ts:11-31 (handler)

  The main handler function getSystemDiagnostics that runs a PowerShell diagnostic script, processes results, and formats a comprehensive system health report.

  export async function getSystemDiagnostics(args: { daysBack?: number; detailed?: boolean }) {
      const daysBack = args?.daysBack || 7;
      const detailed = args?.detailed || false;
      
      const params = {
        DaysBack: daysBack,
        JsonOutput: true,
        ...(detailed && { Detailed: true })
      };
  
      const result = await runPowerShellScript(DIAGNOSTIC_SCRIPT, params) as AllTypes.DiagnosticResults;
