/**
 * Composition root for the `cotal` operator CLI, published as `cotal-ai`. Importing an
 * implementation self-registers its commands into the shared registry — base mesh commands
 * plus `spawn`/`console` (@cotal-ai/cli) and the manager's control plane + daemon runners
 * (@cotal-ai/manager). The root just picks which surfaces to pull in; `runCli` resolves
 * whatever registered. A new surface (another connector, a control client …) is one more import line.
 *
 * A daemon entry is the exception: it runs one command for the life of its process, so it imports
 * only the surfaces that command needs (see the providers below), never the whole CLI.
 *
 * Reached only via ./cotal.ts, which runs the Node-version preflight first: everything imported
 * here requires Node >= 22 (the UI stack and the bundled nats-server optional dep), so this module
 * must never be the executable entry — importing it on an old Node crashes at parse time.

  // runtime and its zod copy into CLI startup, and a renderer needs none of it.

// materializes each lazily when a command resolves it; the default agent is `COTAL_DEFAULT_AGENT`
// (else claude), resolved manager-side. The old `"cotal"` default-agent alias is gone with them.
//
// Bare `cotal` prints the entry screen; explicit `cotal setup` runs guided setup. The published binary is
// the ONE composition root that loads operator-installed extensions (`cotal ext add …`) — commands,
// runtimes, connectors, and local process components all self-register from those packages. Library
