🚀 Add auto-release workflow for GitHub Actions

✨ Implemented a new GitHub Actions workflow for automatic releases:
- 📅 Triggers on push of version tags (v*)
- 🏷️ Creates/updates a base version tag and release
- 📝 Generates changelog from commits since last tag
- 🔄 Updates existing base release or creates a new one
- 📦 Creates a full version release with detailed changelog
- 🔒 Configures appropriate permissions for release creation
