/**
 * completion.ts — Citty command definition for `woco completion`.
 *
 * Wraps the existing cmdCompletion(), installCompletions(), and
 * uninstallCompletions() with citty's defineCommand() for typed args.
 * Config-independent: does not require project initialization.
 *
 * Routes sub-actions:
 *   - `woco completion install`     → installCompletions()
 *   - `woco completion uninstall`   → uninstallCompletions()
 *   - `woco completion bash|zsh|fish` → cmdCompletion({ shell })
