feat: add email outreach CLIs for backlink building

Add 4 new zero-dependency CLI tools for email outreach: - hunter.js: Email finding/verification via Hunter.io (query param auth) - snov.js: Email finding + drip campaigns via Snov.io (OAuth2 auth) - lemlist.js: Cold email campaigns via Lemlist (Basic auth) - instantly.js: Cold email at scale via Instantly.ai (query param auth) Includes integration guides and registry/README updates.
