BitBooth Webhook Signature Verify: pay 0

BitBooth Webhook Signature Verify: pay 0.001 USDC, verify a webhook signature against the provider's canonical HMAC scheme. Supports stripe, github, vercel, cdp, slack, and generic HMAC-SHA256. Constant-time compare, clock-skew tolerance on timestamp-bearing providers (Stripe / Slack / CDP). Stateless — caller supplies their secret in the request body, we never store it.
