Record and surface request first-token latency and tool processing duration in task logs. - Add optional agent log timing fields and persist them in file-backed task logs. - Track Time To First Token from the first visible model output per agent logger request. - Track FIFO tool durations for tool result and error rows without storing sensitive payloads. - Render TTFT and duration badges in task chat and agent log viewers with regression coverage. - Document the new persisted timing fields and add a patch changeset for the CLI package.
