Two-Track Package Messaging + NuGet Dependency Fix (v1.51.0)

Two-track install table β€” README.md, all three ResultFlow NuGet READMEs, and the VSIX README now present a clear Track A / Track B choice:

Track A Track B
Use when Using REslava.Result Any other Result library (ErrorOr, LanguageExt, FluentResults, custom)
Install REslava.Result + REslava.Result.Flow REslava.ResultFlow
Analysis Full semantic β€” typed error edges, type travel, FAIL annotation Syntax-only β€” library-agnostic, convention file
Diagram constants _Diagram Β· _TypeFlow Β· _LayerView Β· _Stats Β· _ErrorSurface Β· _ErrorPropagation _Diagram Β· _TypeFlow

NuGet transitive dependency fix β€” REslava.Result.Flow, REslava.Result.Analyzers, and REslava.Result.AspNetCore now correctly declare REslava.Result as a NuGet transitive dependency in their .nuspec. Previously, SuppressDependenciesWhenPacking=true blocked the dep from appearing; installing these packages did not automatically bring in REslava.Result. Stale REslava.Result.SourceGenerators.Core v1.9.0 reference also removed from REslava.Result.AspNetCore.
