better-auth-bnpl

Wires the better-auth-bnpl plugin (Tabby + Tamara buy-now-pay-later for Better Auth) into an app — provider map, checkout, options picker, orders, webhooks, admin, schema generation, and the secrets each provider needs. Use when the user asks to add BNPL / Tabby / Tamara to a Better Auth app, install or upgrade better-auth-bnpl, configure BNPL credentials or webhooks, or debug an existing install.
