Adds OutlineHandler.cs to the Roslyn helper using CSharpSyntaxTree.ParseText and manual syntax tree traversal (no solution load required). Extracts namespaces, types, method/property/field/event signatures and line numbers without method bodies. Handles file-scoped namespaces, generics, records, nested types, partial classes, top-level statements, and [Obsolete] markers. Adds Microsoft.CodeAnalysis.CSharp 4.13.0 as the sole new NuGet dependency (pure parser, no MSBuild coupling). Go side adds Outline() client method, OutlineResult/Type/Member types, outline.go command, and WriteOutline formatter. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
