Pull Request Overview

This PR enforces a consistent curly brace style across the codebase by adding curly braces to all single-statement control structures and configuring ESLint to enforce this pattern going forward.

• Adds curly braces around all single-statement if/for/while blocks
• Updates ESLint configuration with the "curly": ["error", "all"] rule
• Maintains consistent code style and improves readability
