Initial commit: managed .NET 10 AVEVA Historian SDK + reverse-engineering toolkit

Full read-only SDK (src/AVEVA.Historian.Client) implementing the CLAUDE.md required surface against AVEVA Historian's binary WCF protocol — no native AVEVA runtime dependency. All operations live-verified against a local Historian: - ProbeAsync, ReadRawAsync, ReadAggregateAsync, ReadAtTimeAsync, ReadEventsAsync - BrowseTagNamesAsync, GetTagMetadataAsync (17 native data-type codes mapped) - GetConnectionStatusAsync, GetStoreForwardStatusAsync, GetSystemParameterAsync - 108/108 unit + integration tests pass Includes the reverse-engineering toolkit (tools/AVEVA.Historian.ReverseEngineering) used to decode the protocol: WCF probes, IL inspection via dnlib, and IL-rewrite instrumentation (instrument-wcf-{write,read}message etc.) plus the .NET Framework trace harness (tools/AVEVA.Historian.NativeTraceHarness) for parity testing. Sanitized handoff evidence under docs/reverse-engineering/. Native AVEVA binaries (current/, aveva-install-x64/, aveva-install-x86/) are gitignored — fetch separately from the AVEVA installer.
