Build fails on main due duplicate requestToken declaration in MCP status handler

[Widthdom]

dotnet test tests/CodeIndex.Tests/CodeIndex.Tests.csproj currently fails on the latest origin/main checkout with:

src/CodeIndex/Mcp/McpToolHandlers.cs(3180,17): error CS0128: A local variable or function named 'requestToken' is already defined in this scope

The working branch has no diff in src/CodeIndex/Mcp/McpToolHandlers.cs relative to origin/main, so this appears to be an existing main-branch compile break rather than part of the current issue-fix scope.

Working on this as part of PR #3860, since the duplicate requestToken declaration is currently blocking the PR pipeline before tests can run.
