PauseEvent

Event representing a tool call executed by an ACP server.

Captures the tool name, inputs, outputs, and status from ACP ToolCallStart / ToolCallProgress notifications so they can be surfaced in the OpenHands event stream and visualizer.

This is not an LLMConvertibleEvent — ACP tool calls do not participate in LLM message conversion.
