chore(config): add support for custom distDir in dev mode (#903)

Added logic to conditionally set `distDir` to `.next-dev` for
development environments, enhancing separation of dev and prod builds.
Updated `.gitignore`, ESLint ignores, and `tsconfig.json` includes
accordingly.

## Summary by CodeRabbit

* **Chores**
* Standardized development build output directory to “.next-dev” for
docs and UI apps.
* Updated ignore rules to exclude “.next-dev” in project and app-level
.gitignore files.
  * Added “.next-dev” to ESLint ignore patterns.
  * Extended Turbo build outputs to include “.next-dev/**”.
* Updated TypeScript configs to include “.next-dev” type outputs and
generated content types.
  * Reordered TypeScript include entries without changing behavior.
