/**
 * Cleanup domain — preview + execute.
 *
 * Two tools cover the destructive hygiene surface:
 *
 *   - `cleanup_preview` (read) — runs any cleanup verb with
 *     `whatIf: true` so the agent can show the user what would change
 *     before asking for write authorization. No tenant mutations occur.
 *
 *   - `cleanup_execute` (write) — single destructive entry point,
 *     discriminated on `verb`. Honors the per-call `allowWrite` gate
 *     enforced at dispatch, the `whatIf` plan-only flag, and per-verb
 *     blast-radius caps (`max*` options forwarded to the underlying
 *     library). Every verb returns a per-action list so the caller can
 *     inspect what actually applied.
 *
 * Verbs map 1:1 with the `scai hygiene cleanup` CLI verbs whose library task
 * honors `--what-if`. The interactive-keep mode for `duplicates` stays
 * CLI-only because it requires per-group keystroke selection.
