Function dispatch_tools

    agents: Query<'_, '_, (Entity, &AgentState, &StageInference, &InferenceResult, &mut ContextWindow, Option<&ToolResultRoutingComponent>, Option<&ToolSensitivities>, Option<&mut TaintGate>, Option<&GateResolved>, Option<&GateAutoApprove>, Option<&InFlightWork>), With<ReadyForTools>>,

Tool-dispatch system: for each ReadyForTools agent, apply its context_* tool calls inline (they mutate the ECS window) and hand the rest to the sequential tool lane, moving it to AwaitingTools. If a batch is all context tools there is nothing for the lane, so the results are applied immediately and the agent loops straight back to ReadyToInfer. The lane serializes execution, so there is no permit gate - every ready agent is enqueued in turn.
