Cross-device interface metadata listing — answers 'what interfaces are tracked across the fleet, named like X, on device Y?'. Wraps GET /api/interfaces/all, which returns logging-enabled interfaces across every device the user can see (tag-scoped server-side via withUserTags).
**Metadata only.** Each row carries: id, device_id, device_label, name, interface, description. The upstream endpoint does NOT return status, octets, errors, MTU, or speed — for per-interface stats, the LLM should follow up with device_get(id, interfaces=true) on the specific device, which surfaces the latest snapshot of those metrics. We don't fabricate the missing fields here.
Filters (client-side, AND-combined): device_id (limit to one device), search (case-insensitive substring on name / description / interface / device_label).
Pagination: per_page defaults to 50 (max 200). On installs with tens of thousands of interfaces, page through results — the upstream endpoint returns the full list in one shot.
Permission: devices. Examples:
interfaces_search({device_id: 42})
interfaces_search({search: "WAN"})
interfaces_search({search: "Te1/0", per_page: 10})
