Judge0 for HUEL OJ

Note: This is a customized, lightweight fork of Judge0, maintained by Yozuru.

This version is specifically optimized for Henan University of Economics and Law Online Judge (HUEL OJ). It strips away commercial features and marketing content to focus purely on performance, stability, and the specific academic needs of our university's grading system.

Key Changes in v1.14.0

• Core Upgrade: Ported to Ruby 4.0 and Rails 7.2 for improved performance and modern standards.
• Lite & Clean: Removed unnecessary dependencies and promotional material.
• Infrastructure: Optimized for strictly sandboxed execution using isolate with cgroups v2.
• Custom Languages: Curated language list specific to our curriculum.
