Pull Request Overview

This PR updates the codebase to utilize C++ ranges for cleaner and more modern algorithm calls. The changes focus on replacing traditional iterator-based constructs (such as std::any_of and std::find_if) with range-based equivalents to improve readability and maintainability.

• Updated header inclusions to include where needed.
• Replaced iterator-based algorithm calls with std::ranges and std::views for clarity.
• Adjusted substring operations for percent encoding improvements.

@anonrig It is an issue with older LLVMs under Linux. I have changed the code, it should resolve the issue.
