FOCAS — retire Tier-C split, inline managed wire client, make read-only

Migration closes the FOCAS Tier-C architecture. OtOpcUa previously had
`Driver.FOCAS.Host` (NSSM-wrapped Windows service loading Fwlib64.dll via
P/Invoke) + `Driver.FOCAS.Shared` (MessagePack IPC contracts) + a C shim
DLL stand-in for unit tests. All of it is deleted; the driver is now a
single in-process managed assembly talking the FOCAS/2 Ethernet binary
protocol directly on TCP:8193.

Architecture

- Pure-managed `FocasWireClient` inlined at `src/.../Driver.FOCAS/Wire/`
  (owner-imported — see Wire/FocasWireClient.cs for the full surface).
  Opens two TCP sockets, runs the initiate handshake, serialises requests
  on socket 2 through a semaphore, closes cleanly with PDU + socket
  teardown. Both sync `IDisposable` and async `IAsyncDisposable`.
- `WireFocasClient` (same folder) adapts the wire client to OtOpcUa's
  `IFocasClient` surface — fixed-tree reads, PARAM/MACRO/PMC addresses,
  alarms. Writes return `BadNotWritable` by design — OtOpcUa is read-only
  against FOCAS.
- `FocasDriverFactoryExtensions` now accepts `"Backend": "wire"` (default)
  and `"Backend": "unimplemented"`. Legacy `ipc` and `fwlib` backends are
  rejected at startup with a diagnostic pointing at the migration doc.

Deletions

- `src/ZB.MOM.WW.OtOpcUa.Driver.FOCAS.Host/` — whole project + Ipc/,
  Backend/, Stability/, Program.cs.
- `src/ZB.MOM.WW.OtOpcUa.Driver.FOCAS.Shared/` — Contracts/, FrameReader,
  FrameWriter, whole project.
- `tests/...Driver.FOCAS.Host.Tests/` + `.Shared.Tests/` — whole projects.
- `src/.../Driver.FOCAS/FwlibNative.cs` + `FwlibFocasClient.cs` — 21
  P/Invokes + 7 `Pack=1` marshalling structs + the Fwlib-backed
  `IFocasClient` implementation.
- `src/.../Driver.FOCAS/Ipc/` + `Supervisor/` — IPC client wrapper +
  Host-process supervisor (backoff, circuit breaker, heartbeat, post-
  mortem reader, process launcher).
- `scripts/install/Install-FocasHost.ps1` — NSSM service installer.
- `tests/.../Driver.FOCAS.Tests/{IpcFocasClientTests, IpcLoopback,
  FwlibNativeHelperTests, PostMortemReaderCompatibilityTests,
  SupervisorTests, FocasDriverFactoryExtensionsTests}.cs` — tests that
  exercised the retired surfaces.
- `tests/.../Driver.FOCAS.IntegrationTests/Shim/` — the zig-built C shim
  DLL that masqueraded as Fwlib64.dll.

Solution changes

- `ZB.MOM.WW.OtOpcUa.slnx` drops the 4 retired project refs.
- `src/.../Driver.FOCAS.csproj` drops the Shared ProjectReference, adds
  `Microsoft.Extensions.Logging.Abstractions` for the optional `ILogger`
  hook in `FocasWireClient`.
- `src/.../Driver.FOCAS.Cli.csproj` drops the six `<Content Include>`
  entries that copied `vendor/fanuc/*.dll` into the CLI bin. CLI now uses
  `WireFocasClient` directly.
- `FocasDriver` default factory flips to `Wire.WireFocasClientFactory`.

Integration tests

- New `tests/.../Driver.FOCAS.IntegrationTests/` project covering fixed-
  tree reads (identity, axes, dynamic, program, operation mode, timers,
  spindle load + max RPM, servo meters), user-authored PARAM / MACRO /
  PMC reads, `DiscoverAsync` emission, `SubscribeAsync` + `OnDataChange`,
  `IAlarmSource` raise/clear transitions, and `ProbeAsync` /
  `OnHostStatusChanged`. 9 e2e tests against the focas-mock fixture
  (Docker container with the vendored Python mock's native FOCAS/2
  Ethernet responder).
- `scripts/integration/run-focas.ps1` orchestrates compose up → tests →
  compose down. Dropped the shim-build stage + DLL-copy step + the split
  testhost workaround (the latter only existed because of native-DLL
  lifecycle bugs the shim tripped).
- Docker compose collapses from 11 per-series services to one `focas-sim`
  service. Tests seed per-series state via `mock_load_profile` at test
  start.
- Vendored focas-mock snapshot refreshed to pick up upstream's native
  FOCAS/2 Ethernet responder (was 660 lines, now 1018) — the
  pre-refresh snapshot only spoke the JSON admin protocol.

Tests

- 145/145 unit tests in `Driver.FOCAS.Tests` pass (was 208 pre-deletion;
  63 removed tests exercised the retired IPC/shim/supervisor/Fwlib
  surfaces).
- 9/9 integration tests pass against the refreshed mock.
- `FocasScaffoldingTests.Unimplemented_factory_throws_on_Create…` updated
  to assert the new diagnostic message pointing at
  `docs/drivers/FOCAS.md` rather than the now-gone `Fwlib64.dll`.

Docs

- `docs/drivers/FOCAS.md` rewritten for the managed wire topology —
  deployment collapses to one `"Backend": "wire"` config block, no
  separate service, no DLL deployment, no pipe ACL.
- `docs/drivers/FOCAS-Test-Fixture.md` updated — single TCP probe skip
  gate instead of TCP + shim probe; fewer moving parts.
- `docs/drivers/README.md` row for FOCAS reflects the Tier-A managed
  topology (previously listed Tier-C + `Fwlib64.dll` P/Invoke).
- `docs/Driver.FOCAS.Cli.md` drops the Tier-C architecture-note section.
- `docs/v2/implementation/focas-isolation-plan.md` marked historical —
  the plan it documents was executed then superseded by the wire client.
- `docs/v2/v2-release-readiness.md` re-audited 2026-04-24. Phase 5
  driver complement closed. FOCAS change-log entry added.

.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.
Runs the CLI against either the managed wire client (default — Driver.FOCAS.Cli
dials the CNC on TCP:8193 directly, no native dependencies) or the focas-mock
Docker fixture. Hardware-gated by default because the default CncHost is
127.0.0.1; set FOCAS_TRUST_WIRE=1 once -CncHost points at a real CNC, or pass
-ProfileName to run against the Docker sim.
Set FOCAS_TRUST_WIRE=1 when -CncHost points at a real CNC to un-gate.
The script also supports three nice-to-have modes shipped 2026-04-24:
-Series — per-series matrix mode. Accepts a comma-separated list; the
core stages are run once per series, swapping the -Address to
the supplied per-series probe. Fails fast if any series's
configured address is outside the documented range (the driver
itself enforces that at InitializeAsync).
-ProfileName — for use with the Python Docker simulator (see
docs/v2/implementation/focas-simulator-plan.md). Selects a
docker-compose profile + matching -Series. When set, the
FOCAS_TRUST_WIRE gate is considered satisfied because the sim
is a legitimate non-hardware target.
-HandleLeakCycles <int> — stress stage that opens + closes <N> sessions
via the CLI's `probe` command with a short sleep between
cycles. Exercises the Tier-C supervisor's handle-recycle path
without touching user data. Typical values: 1001000. A CNC's
FWLIB handle pool is finite (~510), so this shakes out
handle-leak bugs if either side forgets to free.
