fix(cloud): respect user telemetry opt-out in CloudTelemetryClient

CloudTelemetryClient was ignoring the didUserOptIn parameter and always
returning true from isTelemetryEnabled(), causing telemetry to be sent
even when users disabled it. Now checks VS Code global telemetry level
and stores the opt-in state, consistent with PostHogTelemetryClient.
