Greptile Overview

Greptile Summary

Refactored create-twenty-app to use static template files instead of programmatically generating configuration files. This adds the yarn 4.9.2 release binary, .nvmrc, .yarnrc.yml, eslint.config.mjs, and tsconfig.json as static files that get copied during project creation.

• Added two-step build process in project.json: TypeScript compilation followed by copying static template files to dist
• Added new .gitignore generation in app-template.ts to properly exclude .yarn/* but preserve releases directory
• The .yarnrc.yml now correctly includes yarnPath configuration (was missing before)
• New ESLint config provides comprehensive linting rules aligned with the main project
• Yarn release file is identical to the main project's (verified by checksum)

Confidence Score: 5/5

• This PR is safe to merge - straightforward refactoring that improves maintainability of template generation.
• The changes are well-structured and improve code organization. The yarn release binary matches the main project's checksum, configuration files are standard, and the build process correctly handles copying static files.
• No files require special attention.

@martmull I don't think we want to init git for the user

[martmull]

Why not?

[martmull]

having git initialized is really nice for dev x

[charlesBochet]

is any other project doing that?
