M3 R3.1 capture: instrument-grpc-nonstream IL-rewrite + harness --grpc-rewrite loading

Browse Source 
Adds the dnlib instrument command + harness wiring to capture the two non-streamed-write
buffers from the native 2023 R2 client:

- `instrument-grpc-nonstream <GrpcClient.dll> [out]` injects CaptureLogger.LogByteArray at the
  entry of GrpcHistoryClient.RegisterTags (byte[] tagInfos) and AddNonStreamValues (byte[] inBuff),
  writing the rewrite to docs/reverse-engineering/dnlib-write-copy/grpc2023 (gitignored — derived
  AVEVA binary). dnlib preserves the AVEVA public-key identity so aahClientManaged still binds the
  rewritten copy under the LoadFrom context (no SN re-verification).
- harness `--grpc-rewrite <dir>` probes that dir first, so the instrumented GrpcClient.dll +
  ReverseInstrumentation.dll load ahead of the originals. load-check confirms the rewritten
  strong-named copy binds (HistorianConnectionMode.Historian=2; GrpcHistoryClient RegisterTags +
  AddNonStreamValues present).

Next: capture-write scenario (open write-enabled -> sandbox tag -> read-prime -> AddNonStreamedValue),
which dumps tagInfos + inBuff to the capture NDJSON. Prod write — confirm before running.
