+ * registry's GLOBAL layer, so every agent saw it no matter which preset
+ * composed it — a two-tool benchmark preset actually presented three, and a
+ * locally authored `bash-only` preset presented two. Rendering a question is
+ * a host UI capability; having the tool is an agent capability, and only a
+ * preset decides that. The `tool-ask-user` row belongs in the presets that
+ * want it (and in the TUI composition, which has no presets).
