createReportBundle's addSubagentSessions scanned path.dirname(sessionFile) - the sessions root holding every session in history - and bundled the 10 newest .jsonl files, leaking unrelated sessions' transcripts and bloating archives to tens of MB. Real subagent sessions live inside the current session's own artifacts dir, so recurse that subtree and drop the sessions-root scan entirely. Fixes #8648
