WhatsApp Profile Discovery with Exa Contact Search
This script uses Exa to find phone numbers and email addresses,
then attempts WhatsApp discovery for each found contact.

PROCESS:
1. Extract person's name from LinkedIn profile
2. Use Exa to search for phone numbers and emails
3. For each contact found, attempt WhatsApp discovery
4. Store REAL results only - no fabrication
