This commit introduces .env.production.example and .env.development.example files with API Base URL configuration. It also updates the .gitignore file to ignore the actual .env files, to ensure sensitive data is not tracked.
This revision changes the .gitignore file to focus on core dependencies, testing, production, misc, and vercel. As part of the change, a simplified template has replaced the previous one, removing obsolete or unnecessary ignoring patterns, thus streamlining ignore rules.
