Feat
v1.5: Categorized Monorepo & Multi-Provider Auth/Billing
Packages regroup by domain, and both auth and billing move behind provider abstractions so a deployment can pick its own stack.
- Categorized monorepo layout — packages grouped by domain (design / iam / commerce / integrations / platform / ops / ai)
- Multi-provider auth — Clerk, Better Auth, NextAuth via @nebutra/auth provider abstraction
- Multi-provider billing — Stripe, Polar, LemonSqueezy, ChinaPay, Manual via @nebutra/billing
