Add the spec-required 100/1000-event batching tests and cluster-failover
tests that were missing from the existing C.1 suite:
- AahClientManagedAlarmEventWriterTests: add Large_batch_all_ack_returns_all_true
(batchSize 100 + 1000) and Large_batch_alternating_outcomes_are_positionally_correct
(batchSize 100 + 1000) to satisfy the "1 / 100 / 1000 events" spec requirement;
add Backend_retry_then_succeed_simulates_cluster_failover to cover the
RetryPlease-then-Ack sequence at the IPC layer (unit-level stand-in for the
rig-gated live cluster-failover path).
- SdkAlarmHistorianWriteBackendTests (new file): unit tests that pin the
placeholder backend's RetryPlease-for-every-slot contract (preserves queued
events while D.1 is unresolved); plus two Skip("rig-required") integration
tests covering the live SDK single-event roundtrip and cluster failover via
HistorianClusterEndpointPicker — remove the Skip in PR D.1.
Feasibility note: aahClientManaged.dll IS present in lib/ and referenced in
the csproj; the SDK call site is isolated behind IAlarmHistorianWriteBackend
in SdkAlarmHistorianWriteBackend.WriteBatchAsync (single method, D.1 seam).
The full AahClientManagedAlarmEventWriter implementation was already complete.
Build: 0 errors, 0 warnings.
Tests: 64 passed, 2 skipped (rig-gated), 0 failed.

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.
