D1 Drizzle Schema

Generates Drizzle ORM schemas that actually work with Cloudflare D1's quirks. D1 is SQLite-based but foreign keys are always enforced, there's a 100 bound parameter limit that breaks naive bulk inserts, and you need specific column modes for booleans and timestamps or you'll store garbage. This handles all of that automatically and produces schema files, migration commands, type exports, and a DATABASE_SCHEMA.md for documentation. Use it when scaffolding a new D1 database or adding tables to an existing one. Saves you from the annoying trial-and-error of learning D1's differences from standard SQLite the hard way.
