What it does when it runs

Given named contacts (the output of `prima-committee`), waterfalls across Deepline email-finding providers to find and verify a corporate email — falls through to the next provider on failure until a verified hit, or leaves the field empty if none succeed. Never returns an unverified guess as if it were good data, and never accepts a personal email (gmail, etc.) as the sendable result. Single contacts or a 10-20 sample run freely; a full batch stops first to show contact count, max provider depth, and estimated cost, and waits for explicit approval. Use this after `prima-committee` has named the buying-committee contacts and before `prima-hook`/`prima-draft` need a real address to send to.
