optimize: for loop can be modernized using range over int

[Copilot]

Pull Request Overview

This PR modernizes Go for loops by replacing traditional for i := 0; i < n; i++ patterns with the newer for i := range n syntax introduced in Go 1.22, improving code readability and consistency.

• Modernizes for loops across test files and production code using range over integers
• Updates benchmark functions to use the cleaner range syntax
• Maintains identical functionality while improving code clarity
