How This Affected the ECS Windows Agent

The ECS Windows agent's Execute Command (ECS Exec) capability relies on checking that a set of required SSM plugin directories exist on the host before advertising ecs.capability.execute-command to the ECS control plane. This check happens in appendExecCapabilities() via dependenciesExist(dependencies) in agent/app/agent_capability.go.
