pub async fn initialize_bootstrap() -> Result<(), DomainCheckError>Expand description
Pre-warm the bootstrap cache by fetching the full IANA registry.
Call this before bulk operations (e.g., --all mode) to ensure all ~1,180
TLDs are available without per-TLD network requests.
This is safe to call multiple times — subsequent calls are no-ops if the cache is still fresh (within the 24-hour TTL).
