Stacked on the #474 fix. Worker already has a fake-clock override (set_now_ms_fn) for its own unit tests, but it's #[cfg(test)]-gated and invisible to integration tests under tests/, which link the library normally. Widen it to pub(crate) and add PrecomputeEngine::with_now_ms_fn, a builder that threads a shared clock override down to every spawned worker, so an integration test can drive the wall-clock fallback deterministically through the real ingest pipeline instead of racing a real clock with sleeps. No behavioral change: the override defaults to None and every worker keeps its default SystemTime::now-backed clock unless a caller opts in. Production code never calls with_now_ms_fn.
