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.

Replaces placeholder with full csharp@0.1.0 plugin. Adds helper/
package (locate, process, client, protocol) for JSON-RPC over stdio
to ctx-roslyn-helper. project.go finds .sln (fallback: single .csproj),
loads it, retrieves projectSummary, formats dense markdown with project
details, reference graph, and multi-targeting section.
