Agent Control Plane — hi-fi (wf4.m1)

wf4.m1 — first hi-fi mockup pass built FROM the current wf4 wireframes (the qdash-grouped IA + net-new surfaces). Reuses the wf3.m1 component vocabulary (BudgetMeter, DataSeverityTag, ChartDoughnut, ScoreGauge). First page: Usage Limits (per-user/agent/tool spend ceilings on the Audit→Assist→Enforce ladder).

Phase 3 — hi-fi mockups of the wf3 control plane (real design-system components).
