v0.2.0 — Drizzle ORM bidirectional support

v0.2.0 — Drizzle ORM Bidirectional Support

New

• Drizzle ORM schema → SQL: parse pgTable/mysqlTable/sqliteTable definitions
• SQL → Drizzle ORM schema: generate TypeScript with type-correct column mappings
• Drizzle ↔ Prisma roundtrip: convert between both ORMs via the internal IR
• Supports: pgEnum, serial/bigserial, varchar/text, timestamp/date/time, JSONB/UUID, default values, primary keys, .notNull(), .unique()
• Dialect-aware: pg, mysql, sqlite table factory functions

Fixed

• Drizzle parser/generator were implemented but not registered in the conversion registry (_registry dict), causing all Drizzle-related conversions to raise ValueError("Unsupported format") — now properly imported and registered

Technical

• DrizzleParser: regex-based TypeScript schema parser (handles nested braces, string literals, comments)
• DrizzleGenerator: outputs idiomatic Drizzle ORM schema with runtime-overridable dialect
• 4 new tests: SQL→Drizzle, Drizzle→SQL, Drizzle→Prisma, Prisma→Drizzle (all passing)
• 40/40 tests passing
