Horizon native app testing

Use the separately configured native MCP server for declared iOS and Android tests. Read the app and companion backend instructions before a device run. Read the native app reference for prerequisites, interactive sessions, evidence, and recovery. Use current MCP schemas for arguments.

Use only the approved native device quota and declared loopback ports. A browser quota does not authorize native devices. Keep provider credentials in Horizon. Use one immutable artifact per platform per run and isolated synthetic backends. Observe interactive tests through a live native Device panel in the current workspace. Use horizon-device for viewer presentation checks; use app_* for native input. Do not send native input through a browser or through a viewer's Interact toggle.
