Kimi Code subagent tool calls land in the parent session #184

Kimi Code fires hooks inside subagents with the parent's session id and nothing that marks them as a subagent's, so a subagent's edits and commands are journaled into the parent session and can become steps of its procedure.

Applies to the agent support in #149.

Fix idea: nothing in the payload allows it today. Reading Kimi's wire.jsonl instead (it marks subagents) would, once parsers get the transcript path.
