v5.4.0
**Moves claudebox to `v2.4.5` and both pibox services to `v0.18.4`. Streaming chat completions on all three can now carry the agent's native event records.**
- Streaming requests to `/claudebox/openai/v1/chat/completions`, `/pibox-zai/openai/v1/chat/completions`, and `/pibox/openai/v1/chat/completions` accept `"stream_options": {"include_aicodebox_events": true}`. The response then adds named `aicodebox.native` SSE events next to the normal OpenAI chunks, each wrapping a raw record from the agent. Content chunks and `[DONE]` are unchanged, and a stream without the option carries no extra events. Sending the option without `"stream": true` returns `400`. See `docs/services/claudebox.md`.
- claudebox image bumped `v2.3.10` to `v2.4.5`. A container created from the new image installs Claude Code `2.1.280` on first start. Claude Code lives in the container filesystem, not the config volume, so the new version arrives when the container is recreated.
- pibox image bumped `v0.16.2` to `v0.18.4` for both `pibox-zai` and `pibox`. This updates pi-coding-agent to `0.85.1`.
- No environment variables changed. Existing `.env` files work as they are.
