What
Adds a global cresettings gate
RemoteExecutableWorkflowDONBindingEnabled(defaultfalse).Why
When enabled, it lets the remote executable capability server (in chainlink) reject any request whose
RequestMetadata.WorkflowDonIDdoes not match the authenticated calling DON (msg.CallerDonId). This binds the caller-suppliedWorkflowDonIDto the authenticated sender DON so it cannot be spoofed by a colluding calling DON — a security boundary that capabilities such as vault rely on.The chainlink-side enforcement is a separate PR.
