refactor(driver-historian-wonderware-client): extract WonderwareHistorianClientOptions to .Contracts

Move WonderwareHistorianClientOptions to a new
Driver.Historian.Wonderware.Client.Contracts sibling project. The record
had no using directives and uses only primitive types (string, TimeSpan)
so the contracts project is dependency-free.

Convert one doc-comment reference:
  <see cref="WonderwareHistorianClient"/> → <c>WonderwareHistorianClient</c>
per the approved decision — no compilable usings were present.

The runtime Driver.Historian.Wonderware.Client project gains a
ProjectReference to .Contracts; the .slnx is updated accordingly.
