Add S7TypeMappingTests.cs covering ReinterpretRawValue and BoxValueForWrite —
26 tests verifying every implemented type round-trip (Bool/Byte/UInt16/Int16/
UInt32/Int32/Float32), two's-complement reinterpret semantics (ushort→short,
uint→int), unsupported-type NotSupportedException, and overflow edge cases.
These methods were factored out as internal static in the S7-002/S7-008 commit.

Driver.S7-001: Timer (T{n}) / Counter (C{n}) addresses parsed cleanly but
the read path had no S7DataType or decode case for them, so a Timer/Counter
tag passed fail-fast init and then threw a misleading type-mismatch on every
read. InitializeAsync now runs RejectUnsupportedTagAddresses, throwing a clear
NotSupportedException ("not yet supported", echoing tag name + address) so the
config error fails fast at init.
Driver.S7-006: ShutdownAsync cancelled the probe/poll CTSs but did not await
the fire-and-forget loop tasks before DisposeAsync disposed _gate, letting a
loop iteration mid-semaphore race a disposed object. The probe task is now
tracked in _probeTask and each poll task in SubscriptionState.PollTask;
ShutdownAsync cancels every CTS, awaits Task.WhenAll of those handles with a
bounded 5 s DrainTimeout, then disposes the CTSs and gate. Task.Run is passed
CancellationToken.None so the handle is always awaitable.
Driver.S7-007: a PUT/GET-disabled fault (permanent misconfiguration) was
mapped identically to a transient PlcException — both BadDeviceFailure +
Degraded. ReadAsync/WriteAsync now split the catch via an IsAccessDenied
filter (S7.Net exposes no typed code for AccessingObjectNotAllowed, so the
inner-exception chain is inspected for the "not allowed" marker). Access-denied
now maps to BadNotSupported and Faulted with a config-alert message pointing
at the TIA Portal PUT/GET toggle; genuine device faults stay BadDeviceFailure.
Driver.S7-011: S7Driver ignored driverConfigJson on Initialize/Reinitialize,
so a config change delivered through ReinitializeAsync (the only Core-initiated
in-process recovery path) was silently discarded. Config parsing was factored
into S7DriverFactoryExtensions.ParseOptions; InitializeAsync now re-parses
driverConfigJson and rebuilds _options whenever the document has a real body.
An empty / placeholder document keeps the constructor options.
Adds S7DriverCodeReviewFixTests covering Timer/Counter rejection, config-json
application on Initialize/Reinitialize, and shutdown-drain with active
subscriptions. All 68 S7 driver tests pass.

Group all 69 projects into category subfolders under src/ and tests/ so the
Rider Solution Explorer mirrors the module structure. Folders: Core, Server,
Drivers (with a nested Driver CLIs subfolder), Client, Tooling.
- Move every project folder on disk with git mv (history preserved as renames).
- Recompute relative paths in 57 .csproj files: cross-category ProjectReferences,
the lib/ HintPath+None refs in Driver.Historian.Wonderware, and the external
mxaccessgw refs in Driver.Galaxy and its test project.
- Rebuild ZB.MOM.WW.OtOpcUa.slnx with nested solution folders.
- Re-prefix project paths in functional scripts (e2e, compliance, smoke SQL,
integration, install).
Build green (0 errors); unit tests pass. Docs left for a separate pass.
