/**
 * Remove one content locale's data from a document, in place on the same
 * document, by writing a new immutable version that omits that locale's
 * store rows (every other locale and all non-localized `'all'` rows are
 * carried forward by the storage primitive).
 *
 * The document's source content locale is its anchor (path + source_locale)
 * and can never be removed — rejected up front. The new version lands as the
 * workflow's default status (a fresh draft), exactly like `copyToLocale`: the
 * previously-published version keeps serving — including the locale being
 * removed — until the new version is reviewed and published. The deletion is
 * recoverable: the prior version still holds the locale, so restoring it
 * brings the content back.
 *
 * Flow:
 *   1. `assertActorCanPerform('update')` — removing a translation is an edit.
 *   2. Reject deletion of the document’s source locale.
 *   3. Read the document in the target locale (validates existence; supplies
 *      `originalData` for hooks and the availability set for the presence
 *      check).
 *   4. Reject when the locale has no content to delete.
 *   5. `hooks.beforeUpdate({ …, deleteLocale: { locale } })`.
 *   6. `db.commands.documents.deleteDocumentLocale({ …, status: default })`.
 *   7. `hooks.afterUpdate({ …, deleteLocale: { locale } })`.
