Sequential Execution Option for Runbook "Run All"

NetBrain currently executes all QApps within a Runbook in parallel when the 'Run All' option is used, with no setting to control execution order. This enhancement would introduce an option to run QApps sequentially, allowing each step to complete before the next begins. Sequential execution would benefit customers whose Runbook steps depend on the output or system state established by prior steps, improving reliability for multi-stage automation workflows.
