/**
 * Unified configuration command barrel.
 *
 * `agents config` consolidates the fragmented config surface into one namespace:
 *   - run defaults (model, mode, effort)
 *   - tier overrides (folded into the run namespace)
 *   - interactive host
 *   - browser profile
 *   - local projects root
 *   - per-device config keys
 *
 * The underlying YAML schema is unchanged; this command translates the new key
 * grammar into reads/writes of the existing stores.
