chat via Chrome DevTools Protocol.

`forward_claude`, `list_peers`, `get_peer_health`) over Streamable HTTP on port 3057,
plus the 4 mcp-common baseline tools (`discover_tools`, `get_liveness`, `get_readiness`,
`health_check_all`).

**OS support:** macOS and Windows are fully supported. Linux works against
community-built Electron desktop apps (Anthropic and OpenAI do not ship
official Linux builds), but the shipped selector YAML has only `darwin:`
and `windows:` blocks — Linux operators must add a `linux:` block (see
[Quick start](#quick-start)).
