Resumed tool calls were flat `⚡name arg` rows — no output, not collapsible —
because the resume snapshot (_history_to_messages) dropped each tool's result.
Now the native engine passes `with_tool_output: true` on session.resume and the
gateway folds the tool's redacted+capped result + args into its row, so resumed
turns show `▶ name arg (N lines)` collapsible blocks identical to a live turn.
The flag is OPT-IN: Ink doesn't pass it, so _history_to_messages stays byte-for-
byte unchanged for the Ink path (its expanded verbose-trail render OOM'd on big
output, #34095; the native engine renders tools collapsed, so the capped tail is
safe there). resume.ts maps context→argsPreview, result_text→resultText (label
peeled + envelope stripped), args→argsText — same shape as the live tool part.
py_compile OK. resume tests updated + 1 added (79 pass).
