// Qoder's CLI (qodercli, and qoderclicn for the China site: one build)
// keeps its sessions as Claude Code does, in its folder's projects/: a
// session's <id>.jsonl in its project's folder, its subagents' in
// <id>/subagents/agent-<id>.jsonl, the lines Claude Code's — "user" and
// "assistant" with the Anthropic usage (on a reply's last block only), the
// cwd and the session id on each, "ai-title" and "summary" lines. They are
// read as Claude Code's are. `qodercli --resume <id>` picks one up again.

// QoderDir is the folder of Qoder's build of this id: $QODER_CONFIG_DIR,
// else ~/.qoder, for qoder; $QODERCN_CONFIG_DIR, else ~/.qoder-cn, for
