refactor(Wind): Remove mock sync sleep from MountainSyncHelper

Strip the `Effect.sleep(10)` used as a simulated sync delay and its "Mock sync for now" comment from the `SyncNowEffect` generator. The Mountain, IPC, and Telemetry services are already injected (though currently unused, denoted by underscore-prefixed parameters), and telemetry logging of the sync attempt is in place; the artificial sleep was the last piece of test scaffolding blocking a real sync cycle.

Mountain integration — fetching actual state changes — remains gated by the `// DEPENDENCY: Requires Mountain service integration` placeholder and will be wired in a subsequent change.
