Prisma Generator Postgres Realtime

A Prisma generator (v1.0.0) that transforms your Postgres database into a realtime database by generating SQL migrations (triggers, functions, publication) and a type-safe Prisma client extension for subscribing to row-level changes. It integrates with Prisma's `$extends` pattern and node-postgres (`pg`) for LISTEN/NOTIFY. Unlike raw pg subscriptions or Supabase Realtime, this keeps everything inside Prisma's type system, generates migrations automatically, and supports per-model filtering via optional config. Release cadence: initial release, active development.
