/**
 * CLI plugin for finding unused translation keys.
 *
 * Statically scans the project for `$dictionary(...)` calls, extracts
 * every declared key, and reports the ones that have no quoted-literal
 * reference anywhere else in the source tree. Designed to be wired
 * into `yarn v` (or any verify pipeline) so dead i18n entries can't
 * pile up unnoticed when a feature is removed.
 *
 * Commands:
 * - `alepha i18n check` — report unused translation keys
 *
 * Configuration in `alepha.config.ts`:
 *
 * ```typescript
 * import { i18n } from "alepha/cli/i18n";
 *
 * export default defineConfig({
 *   plugins: [
 *     i18n({
 *       scan: ["src", ".vendor/@alepha/ui"],
 *       dynamicPrefixes: ["archive.type.", "petitions.filter."],
 *     }),
 *   ],
 * });
 * ```
