/**
 * Work Email enrichment. Finds a person's work email from a full name plus any
 * available identifiers (company domain, LinkedIn URL) via a provider waterfall:
 * deterministic finders first (Hunter, Findymail by name then by LinkedIn), then
 * enrichment/reveal providers (Prospeo, Wiza), then People Data Labs as a broad
 * record-match fallback, then Datagma, LeadMagic, Dropcontact, and Enrow
 * as additional finders. Each provider opportunistically uses whatever
 * identifiers the row provides and self-skips when it has none usable, so adding
 * more inputs widens coverage. First email wins; all providers support hosted keys.
