Subject: [PATCH] test: declare client-prereq-cycle-detection capability in
 wrappers

Adds the `client-prereq-cycle-detection` capability to each wrapper's
contract-test service so the sdk-test-harness exercises cycle scenarios
against them. Covers react, react-native, electron, and node-client;
vue has no contract-test service (jest-only), so nothing to declare.

The defensive cycle guard itself lives in the shared
@launchdarkly/js-client-sdk-common package (v1.30.0), which every
wrapper already depends on. Each wrapper's variation() is a direct
passthrough to the shared LDClientImpl, so no wrapper-specific code
changes are needed.
