Move AbLegacyDriverOptions, AbLegacyDataType enum, and AbLegacyPlcFamilyProfile (including AbLegacyPlcFamily enum) to a new Driver.AbLegacy.Contracts sibling project. All three files are zero-dep after splitting AbLegacyDataTypeExtensions (which uses DriverDataType from Core.Abstractions) into a new file that stays in the runtime driver. Drop the doc-comment <see cref="AbLegacyAddress.TryParse"/> reference and replace with <c>AbLegacyAddress.TryParse</c> per the approved decision. The PlcFamilies using directive is retained in the contracts project since both namespaces live there. The runtime Driver.AbLegacy project gains a ProjectReference to .Contracts; the .slnx is updated accordingly.
