--no-clipboard flag to disable clipboard read/write

[mark-e-deyoung]

Problem

clipboard.read exposes current clipboard text to any connected client — which may contain passwords, API keys, or other credentials from paste workflows. No way to disable clipboard access while keeping other automation capabilities.

Proposed Solution

Add --no-clipboard flag that causes clipboard.read and clipboard.write to return E_ACCESS_DENIED.
