Joseph Doherty 8d92e00e38 Task #253 — E2E CLI test scripts + FOCAS test-client CLI
The driver-layer integration tests confirm the driver sees the PLC, and
the Client.CLI tests confirm the client sees the server. Nothing glued
them end-to-end until this PR.

- scripts/e2e/_common.ps1: shared helpers — CLI invocation (published-
  binary OR `dotnet run` fallback), Test-Probe / Test-DriverLoopback /
  Test-ServerBridge (all return @{Passed;Reason} hashtables).
- scripts/e2e/test-<modbus|abcip|ablegacy|s7|focas|twincat>.ps1: per-
  driver three-stage script (probe → driver-loopback → server-bridge).
  AB Legacy / FOCAS / TwinCAT are gated behind *_TRUST_WIRE env vars
  since they need real hardware (#222) or a licensed runtime (#221).
- scripts/e2e/test-phase7-virtualtags.ps1: writes a Modbus HR, reads
  the server-side VirtualTag (VT = input * 2) back via OPC UA, triggers
  + clears a scripted alarm. Exercises the Phase 7 CachedTagUpstreamSource
  + ScriptedAlarmEngine path.
- scripts/e2e/test-all.ps1: reads e2e-config.json sidecar, runs each
  present driver, prints a FINAL MATRIX (PASS/FAIL/SKIP). Missing
  sections SKIP rather than fail hard.
- scripts/e2e/e2e-config.sample.json: commented sample — each dev's
  NodeIds are local-seed-specific so e2e-config.json is .gitignore-d.
- scripts/e2e/README.md: full walkthrough — prereqs, three-stage design,
  env-var gates, expected matrix, why this is separate from `dotnet test`.

Tasks #249-#251 shipped Modbus/AbCip/AbLegacy/S7/TwinCAT CLIs but left
FOCAS out. Since test-focas.ps1 needs it, the 6th CLI ships here:

- src/ZB.MOM.WW.OtOpcUa.Driver.FOCAS.Cli: probe/read/write/subscribe
  commands, AssemblyName `otopcua-focas-cli`. WriteCommand.ParseValue
  handles the full FocasDataType enum (Bit/Byte/Int16/Int32/Float32/
  Float64/String — no UInt variants; the FOCAS protocol exposes signed
  PMC + Fanuc-Float only). Default DataType is Int16 to match the PMC
  register convention.

Full-solution build clean (0 errors). FOCAS CLI wired into
ZB.MOM.WW.OtOpcUa.slnx. No .Tests project for the FOCAS CLI yet —
symmetric with how ProbeCommand has no unit-testable pure logic in the
other 5 CLIs either; WriteCommand.ParseValue parity will land in a
follow-up to keep this PR scoped.

.SYNOPSIS
End-to-end CLI test for the Modbus-TCP driver bridged through the OtOpcUa server.
.DESCRIPTION
Three assertions:
1. `otopcua-modbus-cli probe` hits the simulator
2. Driver-loopback write + read-back via modbus-cli
3. Bridge: modbus-cli writes HR[100], OPC UA client reads the bridged NodeId
Requires a running Modbus simulator on localhost:5502 (the pymodbus fixture
default per docs/drivers/Modbus-Test-Fixture.md) and a running OtOpcUa server
whose config DB has a Modbus DriverInstance bound to that simulator + a Tag
at HR[100] Int16 published under the NodeId passed via -BridgeNodeId.
.PARAMETER ModbusHost
Host:port of the Modbus simulator. Default 127.0.0.1:5502.
.PARAMETER OpcUaUrl
Endpoint URL of the OtOpcUa server. Default opc.tcp://localhost:4840.
.PARAMETER BridgeNodeId
OPC UA NodeId the OtOpcUa server publishes the HR[100] tag at. Set per your
server config — e.g. 'ns=2;s=/warsaw/modbus-sim/HR_100'. Required.
