ToolResult gains an events field (additive, defaults empty) carrying
per-tool audit records when a rein can observe its own inner loop's
individual tool calls -- populated after dispatch_tool returns, not via
a live callback (the contract has no per-event hook). ReinAharness
gains a stream_tool_events flag: when set, passes --stream-tool-events
and parses the tagged {"stream_event": ...} lines back out of captured
stdout into ToolResult.events.
