Plugin eval mock runs can now flag an MCP server as 'withheld' in results

What

When running a mock evaluation of a plugin, the summary of results for each MCP server can now include a withheld: true flag, in addition to the existing replayPinned count.

Why

This lets plugin developers see when a server was withheld during a mock eval run, giving clearer insight into what happened during testing.
