Add `codegen` Support to Studio

[RitoG09]

Generating TypeScript types directly from JSON Schema improves developer experience, supporting codegen would provide a natural extension of existing features.

Maybe, though would it be supporting the right flow? If you would do it with the VS Code extension, you would be essentially promoting users to copy paste the TypeScript code from there? Which you probably shouldn't. If any, they should integrate into some sort of build configuration, potentially powered by jsonschema codegen directly.

Thanks for the clarification. I spent some time looking at how other tools like Prisma handle this ->

e.g., Prisma doesn’t rely on an editor driven flow for code generation. The schema.prisma is the main file and users run prisma generate via cli. That command is typically integrated into package.json scripts (e.g., postinstall, prebuild, etc.) making the process reproducible and CI friendly.

Following the same philosophy, instead of Studio directly generating TypeScript types for manual use, what we can do ->

• Detect the schema file
• Ask for output path and optional type prefix
• Add a jsonschema codegen script to package.json, e.g.

{
  "scripts": {
    "generate:types": "jsonschema codegen schema.json --target typescript --name Person > src/generated/types.ts"
  }
}

• Create the output directory and ensure the generated file is clearly marked as auto-generated.

Now one more thing is, do we really need Studio to implement this, or should this remain purely a CLI-level concern?
