Joseph Doherty a9b585ac5b Task #253 follow-up — bidirectional + subscribe-sees-change e2e stages
The original three-stage design (probe / driver-loopback / forward-
bridge) only proved driver-write → server-read. It missed:

 - OPC UA write → server → driver → PLC (the reverse direction)
 - server-side data-change notifications actually firing (a stale
   subscription can still let a read-after-the-fact return the new
   value and look fine)

Extend _common.ps1 with two helpers:

 - Test-OpcUaWriteBridge: otopcua-cli write the NodeId -> wait 3s ->
   driver CLI read the PLC side, assert equality.
 - Test-SubscribeSeesChange: Start-Process otopcua-cli subscribe in the
   background with --duration N, settle 2s, driver-side write, wait for
   the subscription window to close, assert captured stdout contains
   the new value.

Wire both into test-modbus / test-abcip / test-ablegacy / test-s7 /
test-focas / test-twincat after the existing forward-bridge stage.
Update README to describe the five-stage design + note that the
published NodeId must be writable for stages 4 + 5.

Also prepend UTF-8 BOM to every script in scripts/e2e so Windows
PowerShell 5.1 parsers agree on em-dash byte sequences the way
PowerShell 7 already does. The scripts still #Requires -Version 7.0 —
the BOM is purely defensive for IDE / CI step parsers.

.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.
