/**
 * Builtin `builtin:codex` runtime config: schema type, defaults, and reader.
 *
 * Codex runtime config is owned by this package (the `builtin:codex` provider),
 * not by the Dreamux host config module. It depends only on the shared neutral
 * validation primitives (`@excitedjs/dreamux-utils`), never on
 * `@excitedjs/dreamux` core. The Dreamux host config module re-exports these so
 * the non-builtin callers (doctor, daemon, tests) keep their import paths.
 */
/**
 * Builtin Codex runtime settings under a named `agents[].config` entry (provider
 * `builtin:codex`), referenced by a dispatcher via `dispatchers[].agentRuntime`.
 * Every field carries a built-in default, so an agent that omits any config
 * field runs with these constants. There is no top-level `codex` block anymore;
 * runtime config lives in `agents[]`.
 *
 * `bin` is the dispatcher's Codex binary path; the `CODEX_HOST_CODEX_BIN`
 * environment variable is a host-level override that takes precedence over it
 * (resolved by the codex builtin's `resolveCodexBinPath`).
 * `initialize_timeout_ms` is that dispatcher's handshake timeout.
