/**
 * Device-identity builder for the cross-harness inventory payload

 *
 * Produces the {@link InventoryDevice} half of an {@link InventoryUploadPayload}.
 * Field minimization follows ADR-124: the raw hostname is NEVER sent by default
 * (`hostname_display` is `null` this wave); only a salt-free sha256 `hostname_hash`
 * is included as a soft duplicate-device hint. The hash is not trivially
 * reversible, but a low-entropy hostname is dictionary-recoverable — this is
 * acceptable per ADR-124 because the hash is scoped to the user's own
 * authenticated account, never exposed cross-tenant.

 *   (`inventory.deviceLabel`); there is no dedicated getter in `device-identity`,
 *   so it is read directly from config and capped to `LABEL_MAX`.
 * - `hostname_display` is always `null` this wave (ADR-124 minimization).
