/**
 * Config command — scriptable settings surface (routing-table plan,
 * Ticket 4).
 *
 * Presentation-only over the typed key registry in `src/lib/config-store.ts`
 * (Ticket 3): `resolveConfigKey` / `setConfigValue` / `unsetConfigValue`
 * own validation and atomic persistence. The dispatcher wires production
 * helpers; tests inject doubles.
 *
 * `get` output is ALWAYS redacted: values pass through `redactSecrets`
 * against the merged env's credential values, and credential-bearing
 * field names (e.g. `apiKey`) mask regardless — so a file-stored key is
 * never printable. `set` refuses credential paths outright at the
 * registry layer (API keys never ride argv, AGENTS.md).
