Subject: [PATCH 1/2] feat(detectors): add Nigerian fintech & betting
 credential detector
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds high-signal detector for:
• Paystack (live/test keys)
• Flutterwave/Rave
• Remita merchant+hash
• Interswitch MAC keys
• SportyBet/BetKing tokens

Written by @Lloydcoder (Tinlance) after shipping the same in Nuclei templates.
Zero false positives expected due to keyword pre-filtering.
🇳🇬
