Pull Request Overview

This PR adds enforcement for curly braces on all control statements by implementing the ESLint curly rule with the 'all' setting. The changes ensure consistent code style across the codebase by requiring braces around all control statement bodies, even single-line statements.

Key changes:

• Added the curly: ['error', 'all'] ESLint rule to enforce braces on all control statements
• Updated existing code to comply with the new rule by adding braces to if statements, for loops, and other control structures
• Modified documentation examples to demonstrate the enforced style
