# REPL agent with swappable DeepSeek and local-bash backends. `dsh-stdio-demo`
# supplies the agent-core spine, logging, JSONL persistence, readline UI, and `main` agent.
# HMR remains a leaf because it requires Loader internals; `demo:repl` passes
# `--expose-internals`. The app bin loads the gitignored root `.env`; this file
# reads `DEEPSEEK_API_KEY` and optional `DEEPSEEK_BASE_URL` through `!!js`.

# Hot-module reload for the dev/demo loop (needs `node --expose-internals`).
