Comments looked different depending on the run: tool-using agents got a
collapsed <details> report while text-only replies got a bare one-line <sub>
footer. Every comment now gets the SAME dropdown — summary '🔧 N tool calls ·
in X · out Y · <cost>', body = the tool list (or '(no tool calls)') plus the
full token/cost breakdown.
