[Bug]: USE_ROSLYN can't be referenced when unity-mcp installed via UPM #1295

What happened?

The Roslyn install wizard puts DLLs in Assets/Plugins/Roslyn and docs say to add USE_ROSLYN, but MCPForUnity.Editor.asmdef never references Microsoft.CodeAnalysis.* and so its invisible to the plugins.

Reproduction steps

• Install unity-mcp via UPM
• Use the wizard to install Roslyn
• activate USE_ROSLYN symbol
