notes
The app-server reuses the Codex Rust runtime: same built-in tool set,
same MCP brokering, same wrapped-shell sandbox. Distinct from the CLI
runtime in that consumers drive sessions via JSON-RPC requests
instead of through the bundled TUI. Codex CLI 0.134.0 confirms realtime v1
websocket compatibility and keeps ws:// endpoints available via
`codex app-server --listen`.
