What

Every tool call now watches for cancellation and reports how long it had been running when the abort came in, on both the success and error events.

Details
  • The value is durationMsAtAbort; if the call was already cancelled when it was dispatched, the abort time is the start time, giving zero.
  • Recent-activity records gained the time they were recorded and the tool use id.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
