Tianyi Cui 0e01036a2a test(mcp-client): preserve startup error cause
Strict startup intentionally wraps connection and synchronization failures with the server-qualified activation diagnostic while retaining the original error in Error.cause. The prior assertion checked only the wrapper text, so the causal chain could regress unnoticed and erase the actionable transport failure.

Assert the full wrapper message and object identity of the original connection error in cause. This keeps operator-facing context and the underlying SDK diagnostic independently stable without changing production behavior.
