+// This file holds the compact tool-activity renderers shared by the REPL, the
+// /goal autonomous loop, and /btw side threads: a tool call is shown as a green
+// "→ tool:" line and a tool result as a green "← result:" (or red "← error:")
+// line, with multi-line output collapsed to one line. The todo tool is the one
+// exception — its result is printed in full so the live checklist stays visible.
