.SYNOPSIS
  End-to-end CLI test for the FOCAS (Fanuc CNC) driver.

.DESCRIPTION
  **Hardware-gated.** There is no public FOCAS simulator; the driver's
  FwlibFocasClient P/Invokes Fanuc's licensed Fwlib32.dll. Against a dev
  box without the DLL on PATH the test will skip with a clear message.
  Against a real CNC with the DLL present it runs probe / driver-loopback /
  server-bridge the same way the other scripts do.

  Set FOCAS_TRUST_WIRE=1 when -CncHost points at a real CNC to un-gate.

.PARAMETER CncHost
  IP or hostname of the CNC. Default 127.0.0.1 — override for real runs.

.PARAMETER CncPort
  FOCAS TCP port. Default 8193.

.PARAMETER Address
  FOCAS address to exercise. Default R100 (PMC R-file register).

.PARAMETER OpcUaUrl
  OtOpcUa server endpoint.

.PARAMETER BridgeNodeId
  NodeId at which the server publishes the Address.
