 * Design §4 — the host's product slug, derived at init from its product name and
 * overridable in config. It prefixes every extracted host tool
 * (`maple_invoices_list`) so the model reads them as the product's own actions.
 *
 * Throws rather than falling back, deliberately: a silent fallback would either
 * reintroduce `host_` or invent a slug the host never chose, and because the slug
 * is part of every tool name it is part of every `descriptorHash` — so getting it
 * wrong silently revokes the deployment's grants later instead of failing now.
